Improvised Weapons

You can use an object or a body part as an improvised weapon. You have disadvantage on Fighting tests with an improvised weapon. At the GM's option, the weapon can have other properties (a lit torch might deal your choice of fire damage or mundane damage, for instance) (see Resistance and Vulnerability). You can't make ranged attacks with a part of your body.

The Brawl (1 SP) feat and the Martial Artist (2 SP) feat each improve your ability to fight without a proper weapon.
