Unarmed
Unarmed damage is a form of melee attack damage dealt by a character that does not have a weapon equipped. While it is unusual for most characters to ever use an unarmed attack, character builds based on unarmed damage can be made viable by using

Mechanics
Every character's unarmed attack has a base attack time of 1.2 seconds and a base critical strike chance of 0%. The range of unarmed attacks is 4 units, shorter than the range of any melee weapon. The base physical damage of an unarmed attack varies by class:
| Class | Base unarmed physical damage |
|---|---|
| Witch | 2–5 |
| Shadow | 2–5 |
| Scion | 2–6 |
| Templar | 2–6 |
| Ranger | 2–5 |
| Marauder | 2–8 |
| Duelist | 2–6 |
Unarmed damage is counted under the melee and attack keywords, but not the weapon keyword, and hence is not affected by modifiers to weapon damage, such as Weapon Elemental Damage.
A character with a shield or quiver equipped can still used an unarmed attack.
