Vicious Ferocity is a paragon tier minotaur feat, available to 11th level minotaurs with the ferocity trait.[PH3:189]. It was previously known as Brutal Ferocity, but was renamed due to another feat in the Player's Handbook.[Dr369:9]
Minotaurs with this feat may use an at-will attack in place of the melee basic attack granted by Ferocity.
