[@Wick] Well, if we put some restrictions on it, and the RP-er is good, it could be amazing but not OP! By amazing, I mean amazingly fun to mess with.

For example, kill 10 snakes to get enough to buff one guy to move 0.25 miles per hour faster for 30 seconds! :D

We'd all be sooo sick of it and several of us would want to leave the dude for dead! It'd be great for conflict in the RP! Friction Galore!

Someone'd have to drag this guy around collecting snakes so we can use his power, but unless that essence is stored, it'll be totally useless! He'd have to practice it like crazy to get to a point where people think he's worth the food he gets! I imagine he's gonna get his ass beat if he doesn't have meatshields willing to shelter him :D 

(Yes, he has martial arts, but super powers!)

It'll be great!

 

And I'm glad I made you laugh. I live to entertain :D
