Clobbering

You have been thrown, tossed, dropped, and otherwise concussed more times than you can count. as a result, your skull has become remarkably tough, and your brain much more resilient to impacts to the noggin. 

• Your thick skull has made you a surprisingly good weapon. you deal an additional 2d6 bludgeoning damage when you are thrown, and you deal triple damage to objects and structures when thrown in this way as well. 
• You are immune to being knocked unconscious by head impacts, and you take half damage from attacks such as a mind flayers extract brain attack, which specifically attacks your skull.
