Just thought of this today. We could have options to choose from at the start of the tourney or battle or arena or whatever. But basically here is what I thought of

- mist - aids hiding, similar to all of the guild boost abilities, but comes for free
- sunlight - aids perception, similar to all of the guild boost abilities, but comes for free
- Water - swimming check to move around in multi room tourney
- trees - climbing check to move around in multi room tourney
- webs - escaping check to move around in multi room tourney

These are just a couple ideas to maybe make for a more balanced tourney, I dont know.
