Serious Case of Lycanthropy
You've been bitten by a werewolf and infected with lycanthropy.
Benefit: Whenever you make a non-minion creature winded or kill a non-minion creature, you gain 1 surge.
Drawback: You gain 2 rage at the end of each of your turns whenever you're in combat. You also gain 2 rage every time you gain a surge. If you start your turn with 10 or more rage—or 2 or more rage while in moonlight—you lose all your rage and become a wolfish hybrid until the end of your turn.
While in that form, you have your usual statistics, but you must make a melee free strike against the nearest creature if you can. You can shift up to your speed toward that creature if necessary. If allies and enemies are equally near, you target an ally.
Special: You can't take this complication if you are a fury with the stormwight primordial aspect.
