Ahool Frenzy

You make one willing ahooling or ahool within range become incensed with a bestial bloodlust that drives their movements in combat to greater heights of
savagery, mimicking a barbarian’s rage. Any attacks against or attacks from targets that have been bitten by the enchanted ahool or ahooling gain the rage damage bonus as though the attacker had barbarian levels equal to their Hit Dice. The target of the spell also chooses resistance to bludgeoning, piercing or slashing damage—the target gains resistance to the damage type chosen for the duration of this spell. If you cast this spell on yourself, you can still concentrate on this spell, even though you’re treated as though in a rage. The target of this spell can end it as a bonus action.
