Twelve Days of Sweet Christmas - Hulk Smash Hands

I've decided to do Twelve Days of Sweet Christmas again this year. I'll be focusing on 5e supers this time. 

Hulk Smash Hands (Weapon, Rare, Requires Attunement)

These oversized foam hands have been imbued with a little bit of Santa's magic. The fists deal 1d8 damage and ignore the damage threshold of inanimate objects. Despite being foam, they are not stealthy as the roar or yell "Hulk smash!" each time they strike. To be used as a weapon, the item must be attuned and both fists must be worn.
