Colosseum Tournament

[Reece]

You could probably throw or knock someone into it, or grab them and slam their face against it. If it really is an impenetrable magical wall then that's sure to hurt. Probably not much more than a regular wall, or tree or block of ice or cliff face or any other solid enough object that you could find in any other verse, but still ... there's probably nothing stopping you from using it as such. Like Desco said, using the environment is good RPing.
