You channel primal magic to cause your teeth or fingernails to sharpen, ready to deliver a corrosive attack.
After you make the attack, your teeth or fingernails return to normal.
As I witness my friend's fall, their chest marred by the troll's savage onslaught, a surge of primal determination courses through me. A resonant roar echoes in my mind, ushering magic into my arms. My hands transform, broadening and elongating into formidable, obsidian claws dripping with steaming oil. With a feral snarl akin to a bear's, I lunge at the troll's leg, poised to unleash a primal retribution. "Regenerate THIS!" I cry, embodying the untamed wrath of the wilderness in my vengeful assault.
