I'm playing a bugbear monk currently
So my weapons are currently: my legs.

Humorously though
I had managed to nab some greaves that give me an extra 1d6 if cold damage in unarmed hits.

This means that my legs currently count as a frost imbued mauls. (2d6+dex damahe per hit)

A frozen maul with reach (bugbears got long limbs)

I've told my dm atleast once "I finish him off by kicking them over and Elsa stomping his neck"
