Friction Wraps
Wondrous item, very rare (requires attunement)
You have a +1 bonus to attack rolls and damage rolls with your unarmed strikes while wearing these wraps.
Punching with these wraps generates intense heat that is diffused into the target with each subsequent blow. When you hit with an unarmed strike while wearing these wraps, all subsequent unarmed strikes you make before the end of this turn deal an extra 1d8 fire damage. The damage stacks with itself to a maximum of 3d8 with each hit, and then the heat is released and the process starts over.
