If you set a gust trap on the lower edge of the arena, if people are standing on the edge OUTSIDE, they are dealt damage when the trap is triggered.

Also, you can set traps in the wall.

Edit: Oh, and they're raging gust traps

I'm quite sure this applies to most other AoEs similar to that, but, personally I've only witnessed Explosion doing that.

I was about to post an image of that, but, yup, I just tested that and...that was the result.

Brb murdering everyone in the arena.

EDIT: You can't actually kill them this way. Lame. I mean, GEEZ, if you're going to spend all day standing up againt a wall WHERE PEOPLE ARE FIGHTING, you kind of DESERVE any attacks that manage to hit you, you know? Dev, I'm actually suggesting that this be able to kill people rather than removing it from being able to harm them at all.

This should be corrected.
