You have four arms. You can use each arm as normal but if at least two arms are carrying something, the two remaining arms can only be used to perform the following simple tasks: grapple someone, make an unarmed strike, lift, drop, hold, push, or pull an object or creature. If you are holding weapons or shields with more than two arms, you choose which two arms you use to wield them at the start of your turn. The remaining arms can't do anything that required manual precision, such as using tools or magic items, or performing the somatic components of a spell.
