Also at 3rd level, you gain one of the following features of your choice, your choice will also determine your 14th level Feral feature.
Ravage. When you hit a creature with a melee attack while shapeshifted, you can expend a spell slot to deal extra weapon damage to the target. The extra damage is 2d8 for a 1st-level spell slot, plus 1d8 for each spell level higher than 1st, to a maximum of 6d8.
Frenzy. You can use a bonus action to enter a frenzy while shapeshifted, giving you resistance to bludgeoning, piercing, and slashing damage. Your frenzy lasts for 1 minute. It ends early if you are knocked unconscious or if your turn ends and you haven’t attacked a hostile creature since your last turn or taken damage since then. You can also end the frenzy on your turn as a bonus action. You can use this feature twice. Beginning at 7th level, you can use frenzy three times between rests, and at 15th level, you can enter a frenzy four times between rests. When you finish a long rest, you regain all expended uses.
