You're a regular ray of sunshine

Edit: Above statement aimed at whocares.
Anywho, when people were talking about different Playthrough styles, possibly coming up with unusual ones I wrote this (coincidentally during the arrival of a new member: a Troglodyte)
Animal Kingdom: You can only use Devouring Swarm in a particular context, Possession at low level, non-lethal takedowns, full-spec Agility, Dark Vision, and Healing. No man-made tools can be used. Your decisions have to be motivated by instinct and the mind of an animal. When you use Devouring Swarm, you have to occupy the mind of a rat and join in the crowd to emulate what would otherwise be a happenstance feeding. You can only use runes you find naturally like a dog bringing a stick back to his master and getting a treat for a trick well done. Charms can't be used unless they accentuate this theme, like the white rats being friendlier and replenishing mana when eaten. This reflects your acceptance and savagery as an animal. Food is the only thing you can use to heal yourself and that has to be found food beyond the regen available from Healing.
Edited it just now to reflect new information such as getting rid of powers that were folded into Agility (Celerity and Feather) and to possibly make it a little more viable (Healing). Thought about exempting the sword to emulate a claw, but the runes and charms already seemed like a compromise too much. I left the misconception of the runes to indicate my thought process, but in reality you can invest in powers without visiting the Outsider's realm (unless when they said you could do it during missions it was only when you visit a shrine).
It's a murky concept but I couldn't flesh out my first one:
Wizard of Oz: Use upgraded Windblast to kill people.
Now maybe if Arkane had put in some flying monkeys in this game, I could get some damn traction! Actually this just gave me a thread idea lol. It's stupid but could be fun.
