Unarmed Combat

Version 0.30: This article may not be up to date for the latest stable release of Crawl.

The Unarmed Combat (UC) skill determines the effectiveness of all attacks made with your character's fists, claws, tentacles, and other forelimbs. It increases the damage, accuracy, and speed of your unarmed attacks. It does not boost auxiliary attacks, except for the off-hand punch done without a shield.

Your fists do not normally benefit from weapon brands and definitely don't have artefact properties. However, training Unarmed Combat gives a special bonus to base damage, and can benefit from Transmutations magic.

Useful Info

By default, Unarmed Combat has a base damage of 3, accuracy of +2, base delay of 1.0 decaAut, and a mindelay of 0.5 decaAut (reached at 27 skill). UC itself functions like any other melee weapon, though your fists cannot be enchanted or branded normally.

However, each level of Unarmed Combat skill gives different benefits than other weapon skills:

• Damage: Each level of UC adds +1 to base damage, which is then multiplied by strength and Fighting. This is instead of the usual +2% per level boost.

• Attack speed: Unarmed starts at 1.0 delay, and reaches its mindelay of 0.5 at 27 skill. Therefore, every 5.4 levels of UC reduces attack delay by 0.1 decaAut. Each level of UC reduces delay by ~0.0185 decaAut. For comparison, it usually takes 2 levels for a weapon for the same reduction.

As with weapons, your attack delay will be rounded to an integer aut (i.e. rounding to 0.1 decaAut) in a weighted fashion.

• Increases offhand punch damage and its chance to activate.

The to-hit boost is the same as other weapon skills (+0.5 to-hit per level).

Damage Modifiers

Unarmed Combat's base damage is modified by most transformations and the Claws mutation. In addition, many transformations have special effects.

Condition	Damage	Special
Base damage	3	-
Claws mutation	+2 × level	Wearing gloves negates this Ghoul: Claws 1, Troll: Claws 3
Felid	5	Works well for stabbing
Spider Form	5	Venom
Ice Form	12	Freezing
Blade Hands	22	-
Statue Form	12	All melee damage further multiplied by 150% (All actions slowed by 50%)
Dragon Form	38	Damage post-Claws
Storm Form	2 + pow/3	Cleaving, Electrocution
Lich Form	5	Draining
Bat Form	1
Fungus Form	12	Confusion
Pig Form	1	For damage, skill has 1/5 impact
Tree Form	12
Wisp Form	5	Uses (XL/2) for dmg instead of UC skill

Offhand punch

Offhand punches are an auxiliary attack. Most species are unable to use the offhand punch unless their offhand is empty, which means not wearing a shield or wielding a two-handed weapon. Octopodes get tentacle slaps instead of offhand punches, and may slap even when their offhand is occupied.

If offhand punches/slaps are available, then increasing Unarmed skill increases the chance of an attack. At 0 skill, you have a 5% chance per attack to pass a punch, at 27 skill, you have a 50% chance. It scales linearly, meaning you are 1.67% more likely to proc a punch per skill level.

damage = 5 + (UC / 3)
+ 1d3 × Claws ranks
+ 6 under Blade Hands

Strategy

Unarmed Combat has three main advantages. You don't need to find a weapon, meaning dungeon RNG can't screw you over. Unarmed Combat scales better with skill, so skill 27 unarmed is one of the strongest things in the game. And unarmed can be boosted further with various Transmutations. The downsides are, as mentioned, the inability to enchant or brand fists, and the poor stats at low skill.

The skill scaling of Unarmed Combat can be overrated. At 16 skill:

• Unarmed Combat deals 19 base damage, and attacks at 0.7 delay.
• A morningstar deals 17 damage (after M&F skill), and attacks at 0.7 delay. However, a morningstar can be enchanted and branded.

At high enough skill, (pre-form) Unarmed Combat is around the level of the strongest two-handed weapons. But that's a huge chunk of the game where you are weaker, equal to, or just slightly better than a weapon wielder.

Many forms have high base damage, so you don't need to train that much Unarmed Combat skill to effectively use them. For example, Dragon Form has 38 + UC base damage. Even at 5 UC skill, that's enough to pulverize your enemies. Of course, you should still train at least some skill, to boost accuracy and speed of your attacks.

History

• Prior to 0.17, unarmed combat attack delay was penalized by body armour. Also, trolls' claws could inflict the now-removed bleeding status.
• In earlier versions of Crawl, Unarmed Combat improved the performance of your non-punch auxiliary attacks, giving all melee fighters a reason to train it.
