So, in preparation for Polymorpher inevitably being chosen as the first backer-picked skill tree (it's okay if you disagree, I forgive you

), I'm curious what forms the community can come up with. They can be either serious suggestions or funny ones. It's up to you.
I'll start with a small list of ideas I've had so far:
1. Chicken - become a chicken. Possibly a random result of a polymorph spell failing.
2. Change Race - randomly switch to a different race (including enemy races, such as Orcs). As long as the spell lasts, the player is treated like a member of that race by non-party members.
3. Change Gender - switch genders. Gives access to dialogue and NPC reactions for that gender
4. Sheep - become a sheep, with a 20% chance of becoming a Weresheep instead. Sheep are terrible in combat, Weresheep are devastating.
5. Troll - become a large troll. You deal a massive amount of melee damage and have high armor but are slow and weak to spells.
6. Rock - turn into a large rock. You are immune to all damage (except possibly water spells), but cannot move or take actions.
That's really just scratching the surface. There's a ton of possibilities with this.
