Therianthropy Dominion

You can shift between humanoid, hybrid, and full beast forms without damaging mundane gear. Your natural weapons count as magical for overcoming resistance, and you have advantage on saves against curses, disease, poison, and involuntary transformation from sources below Tier 6.

This power has its own stable page so it can be linked from any character, item, location, story post, bargain, curse, or future reward.
