On Hands (and what PCs can do with them)

Okay, weird post title. Bear with me.

This post was inspired by Warren D.'s post "WHAT'S INTERESTING ABOUT BASIC DUNGONEERING: And what is not" on the I Cast Light! blog. What got me thinking about hands specifically is Warren's thoughts on light and weapons (highlights mine):

Light: Due to torch cost and number per slot, it is easy to carry a lot of torches.

Not interesting: Carrying enough light to last 12-24 turns- easily done

Interesting: When torches extinguish-- like in the middle of a fight or when the goblins you are negotiating with get mad; how many hands in the party are occupied by torches

... 

Weapons: I've yet to find a really good way to do weapons simply outside of 1d6 damage for all types. I don't mind BX's variable weapon damage. And I do like some old rulesets sorta "first strike" if your weapon is larger than an opponents other wise smaller, lighter weapons strike first in subsequent arounds.

So here is what I have got so far: Using a weapon two-handed is a +1 to damage, using an off-hand weapon is +1 to-hit, and a shield is of course +1 AC. I do like that fighters with bows can shoot twice if they did not move and the "cleave" ability.

Not interesting: Weapon factors that are so extensive they require a separate rules discussion, trigger player obsession, and/or orient the whole of gameplay to combat

Interesting: What PCs chose to do with their hands: more armor, more weapons, or more light

What I'm interested in is how player characters choose to use their hands. It's a simple thing, but it's important - a hand can do any of the following things:

• Cast a spell with material or somatic components
• Hold a torch or lantern (providing light with which to see)
• Increase weapon damage (per my rules for variable weapon damage, using two hands increases a weapon's damage die size by one) 
• Increase a weapon's reach (most weapons with the reach property require two hands to use)
• Increase a weapon's range (ranged weapons which require two hands, such as bows, usually have a longer range than those which require one hand, such as thrown weapons)
• Interact with objects (open doors, throw levers, withdraw items from a bag or pouch)
• Make an extra attack (if dual wielding or a monk)
• Provide extra protection (a hand used to hold a shield provides +2 to the character's armor class)
• Use items (drink a potion, read a scroll, activate a wand, etc.)

It's something many DMs might not even think about, and I suspect that most modern DMs view it as one of those things - like encumbrance - which is too onerous to keep track of, and simply don't, beyond "Is the character dual-wielding, two-handing, or using a shield?" I have certainly forgotten about it a good number of times. In fact, when thinking about this, I realized that in a recent AD&D 2e session, I forgot about something very important - light.

Who is Carrying the Light?

The player characters were exploring a network of subterranean tunnels made by a brood of ankhegs. When the party first entered the tunnels, I said, "It's dark, so you'll probably want a light source. Who is carrying the light?" Then, when the party had its climactic battle with the ankheg brood, I never once considered the issue of light. Characters were firing bows, dual wielding, two-handing, and wielding shields. Who was carrying the light? Could the characters even see? I don't know.

When not in combat, the question of who is carrying the light isn't incredibly important. One might as well assume that all of the characters are carrying light unless they state otherwise. Characters might place a torch in a sconce when exploring a room or put it on the ground while they check a chest for traps. True, monsters hidden far away in the dark might target the torchbearer specifically, but in that case, the DM can simply check with the players who exactly is carrying the light before springing the ambush, after which the specifics become more crucial.

Once combat begins, it becomes very important who is carrying the light, because that character can't use their light-carrying hand to cast spells, wield a weapon with both hands, interact with other objects, duel wield (aside from using the torch as a weapon), wield a shield, or use items. That character is making a choice to benefit the rest of the party (by providing light) at the expense of their own tactical versatility. It's part of what makes light-providing spells, weapons, torchbearers, and the like valuable - they can provide light without occupying a hand.

Furthermore, the light source typically moves with the torchbearer, unless the torchbearer drops their torch on the ground in order to free up their other hand. Monsters may attempt to attack the torchbearer and snuff out the light. So, keeping track of who is carrying the light in these scenarios is very important. 

Stow, Drop, and Draw

In D&D 5e, a character can interact with one object for free on their turn, as part of their attack or move action (PHB, page 190). This includes drawing a weapon as part of the action they use to make an attack, opening a door as they move through it, picking up a dropped item, stowing an item, or withdrawing a stowed item. Redditors will happily say that according to the rules, a spellcaster wielding a sword and shield can drop their sword (no action required), freeing up a hand to cast a spell, then immediately pick up the sword again (using their free object interaction).

I hate this. It's stupid. Changing what hand is doing what is a tactical choice. It should have benefits and drawbacks like any other.

Baldur's Gate 3 is the current hotness as far as video games based on 5e go, but another 5e-based game, Solasta: The Crown of the Magister, is much better at little rules minutia like this. In Solasta, each character has weapon sets - a primary weapon set, a secondary weapon set, and a light source set. A character can switch between sets once on their turn.

So if a character is wielding a sword and shield, but wants to make a ranged attack, they switch to their longbow. After attacking with their longbow, they cannot then switch back to their sword and shield to benefit from the improved armor class. If light is an issue, the character can switch to holding their sword and torch, but cannot then switch back to their sword and shield.

This is more or less how I do it in my games, although locking characters into using predefined "weapon sets" is not exactly lifelike. Instead, I implement a stow/drop/draw action, which allows a character to switch what they're holding in each hand once per turn. They can drop their torch and draw another weapon, stow their sword and draw their wand, stow two items to free up both hands, or any combination of those things, so long as the item being held or not is interacted with just once, and the hand switches between only two items per turn. That means no dropping an item to do something with the hand and then picking the item right back up again.

To Two-Hand or Not to Two-Hand

A character who chooses to wield a two-handed weapon is making a deliberate choice. They are doing more damage if they hit, but they are sacrificing increased armor class (from a shield) and number of chances to hit (a dual-wielding character is making an extra attack each round). 

Only, are they actually doing more damage than a dual-wielding character? Using my own rules for variant weapon damage, a character wielding a heavy martial weapon with two hands does d12 damage. A character wielding a light martial weapon in each hand does d6 damage with each. If they hit with both, they do an average of 7 damage, versus the two-hander's average 6.5. Not a huge difference, but it's there.

On top of that, normally, the player does not add their character's Strength or Dexterity modifier to the damage roll from their off-hand weapon, but the two-weapon fighting style allows them to do so, which can make the disparity greater. The dual-wielder also has an extra chance to score a critical hit.

But aha, two-handed weapons only require two hands when making an attack (PHB, page 146)! The second hand is free for the rest of the character's turn, allowing them to manipulate objects, draw items, and the like. If they can cast spells, they might also use their now-free hand for that (more on that later). If the dual-wielder wants to free up a hand, they have to use their stow/drop/draw action on that turn to do so, then use their stow/drop/draw action again on their next turn to switch back. Not a huge difference, but it's there.

Shields

Shields might be an exception to the stow/drop/draw action rule. In 5e, shields require a full action to don or doff (PHB, page 146). This feels overly punitive to me. I would rule that a character could switch their shield out for another item as if that hand was holding anything else. Maybe this isn't realistic (assuming the shield is strapped to the arm), but the gamey, mechanical tradeoff decision from round to round is what I'm interested in here, not realism.

This requires another change - in 5e, a character can benefit from a shield even if they're not proficient with shields. Here's the tradeoff: "If you wear armor that you lack proficiency with, you have disadvantage on any ability check, saving throw, or attack roll that involves Strength or Dexterity, and you can't cast spells" (PHB, page 144). 

That above rule doesn't matter (aside from making saving throws) if the character has already taken their action that turn, meaning a character without shield proficiency could take their action as normal, then whip out a shield to benefit from the extra AC. I don't want that.

So if we remove the action required to don or doff a shield, we have to go a bit further and say "You do not benefit from the bonus to Armor Class when wielding a shield with which you are not proficient." Easy.

The Buckler Shield

One thing I miss from AD&D is different types of shields. 2e has buckler shields, small shields, medium shields, and body shields. I've simplified this a bit in 5e, introducing light (buckler) shields, medium (standard) shields, and heavy (body) shields. 

A character no longer needs proficiency in shields to use one - they just need proficiency in the corresponding armor type. This means that classes which don't normally get to use shields (most bards, rogues, and warlocks) can now use some certain shields, which doesn't bother me.

Standard shields work the same as the typical 5e shield. Body shields are similar, but against ranged attacks from the front and flanks, the character is treated as having three-quarters cover (+5 to AC, instead of the +2 typical of shields).

The buckler is the important shield when it comes to the discussion of hands, because it's light and fastens to the forearm, allowing the hand of the shield arm to be used to do things like fire a bow or crossbow, cast a spell, hold a torch, open a door, or the like. So the character wielding a buckler never needs to worry about stowing, dropping, or drawing their shield.

The tradeoff is that the buckler shield only grants the +2 bonus to Armor Class against one attack per round, and only if the character uses their reaction. It comes in handy (haha), but only if the character's reaction isn't already spoken for, and it's still not as good as having a proper shield.

The Components of a Spellcaster

Finally, I want to talk about spellcasting components. There are three kinds of spell components in D&D 5e: verbal, somatic, and material (PHB, page 203). Every spell in D&D requires at least one of these components, but more often, some combination of two or all three components in order to cast. 

Verbal components are "mystic words" which are spoken aloud as the spell is cast. It's not enough to simply say the words - the combination of sounds requires "specific pitch and resonance" to "set the threads of magic in motion". It's why, in my opinion, a character cannot "quietly" or "stealthily" cast a spell. Uttering the verbal components is loud and showy - it's evident to everyone present that a spell is being cast, disgraced 5e designers be damned.

Somatic components "might include a forceful gesticulation or an intricate set of gestures". Material components are "particular objects" but can be substituted by a component pouch or spellcasting focus so long as the components has no cost and isn't consumed by the spell.

Here's where we get to hands: To cast a spell with somatic components, "the caster must have free use of at least one hand". To cast a spell with material components, "a spellcaster must have a hand free to access [the] material components". However, the hand used to access the material components "can be the same hand that [the caster] uses to perform somatic components".

It used to be that a caster's whole body had to be free to cast a spell. A spellcaster casting a spell with somatic components couldn't just wiggle their fingers. Their whole body had to move. They had to do a dumb little dance. A spellcaster could not move on the same turn they cast a spell. If they were on a ship in the middle of a storm, the rest of the party would have to brace them to hold them still so that they could cast without being thrown around the ship. This, along with proper Vancian spellcasting and simultaneous actions in combat - allowing spellcasters to be interrupted while casting - was a huge element of reigning in the power of spellcasters. 

5e has a much different conception of spellcasters. They're basically hyper-mobile artillery. They can run, ride, and fly around casting spells, and all the while, they only need one hand free. They can be restrained by a titanic boa constrictor and can still cast spells with somatic and material components, so long as they can wiggle their fingers.

I personally rule that a spellcaster can't cast spells with somatic components if they're, for example, grappled or restrained, and in that case, they also can't cast spells with a material component unless those materials are already in hand.

I'm inclined to take it a step farther. What if spellcasters needed one free hand for somatic components, and another for material components? Casting a spell which requires both is a full-body action, meaning the character has to stow or drop whatever other items are occupying their hands before they cast.

Unfortunately, the characters who would suffer most from this aren't the dedicated casters, who probably aren't holding much other than a spellcasting focus anyway - the true victims are those that straddle the line between fighting and spellcasting: artificers, clerics, druids, paladins, and rangers. These characters are spellcasters as well as characters that want to wield weapons and, often, shields.

Most of these classes have features which would mitigate the impact of this effect, allowing them to substitute some other item for a spellcasting focus. Artificers can use infused items as spellcasting foci, meaning that an artificer could infuse their weapon or shield, using it for their material components. Clerics and paladins can etch their holy symbol into a shield or, even better, simply wear it visibly on their person. Druids and - as of Tasha's Cauldron of Everything - rangers can use a druidic focus, which can be a staff, which is also a weapon (although maybe not the preferred one). 

In baseline 5e, this allows each of these character types to wield a useful item while still casting spells which require both somatic and material components (oddly, if the spell only requires a somatic component, they still need a free hand). If we change the rule to require one free hand for each of these components, then they at least need one less hand free.

These classes can also benefit from taking the War Caster feat, which eliminates the need for a free hand to use somatic components, so long as the character is wielding weapons or a shield in one or both hands (my reading of it is that the character couldn't cast a spell requiring somatic components while holding a torch in one hand and holding a potion in the other, for example).

Certain subclasses suffer more greatly - those classes which normally don't cast spells, but have subclasses which do, such as the eldritch knight fighter or the arcane trickster rogue, or those classes which normally don't wield weapons, but have subclasses which do, such as the swords and valor bards and the hexblade warlock. Since 5e is designed in such a way that casting spells with somatic components, material components, or both requires just one hand, this isn't normally a problem. If we require them to use both hands, they become much more limited. If I were to implement the house rule I'm proposing, I would likely give these subclasses some extra feature that allows them to use a weapon or shield as a focus.

Overall, I've not totally sold myself on making this change. It's not like changing a single spell or the way a class feature works, which is relatively easy - it's changing the base rules about how spellcasting as a whole works, which potentially has tons of knock-on effects. 

I'm not particularly interested in going through the whole spell list and analyzing the edge cases of which spells become more or less effective with different classes and subclasses depending on what they can and can't use as a spellcasting focus. It's the kind of thing that would require playtesting. Maybe next time I run a 5e game, I'll try it. Or maybe by then I'll have decided I don't really care.

The important take away is that I'm trying to pay more attention to what my players' characters are doing with their hands. Doing so generates interesting round-by-round decision points (holding a light source, choosing weapons, using a shield, and casting spells are all meaningful tradeoffs). This, and a healthy dose of common sense, reigns in more powerful character concepts, such as spellcasters (a wizard can't cast elaborate spells while being throttled by a tentacled beast). That at the very least is worth considering.
