Wolf Ears

Wolf Ears can't be crafted or bought. Every Fashion Critic drops exactly one pair, and Looting doesn't change that.

Hostile mobs within 24 blocks get a glowing outline that only you see, also through walls. That is 8 blocks further than Cat Ears and twice the reach of the Cyber Visor. Your melee and projectile damage to skeletons of every kind (entity tag #minecraft:skeletons) is multiplied by 1.25.

16 Drip is the most a head accessory gives: the other ears have 10, the headphones 12.

The ears themselves turn toward hostile mobs within 16 blocks and pick out skeletons first, from 24. The rest of how ears move is on the Cat Ears page.
