I find that saying “causes that creature’s health to reduce” (or similar phrases) on every single occasion that such things are required is a bit wordy, and feel these definitions could be convenient in the future. Orcs can’t attack each other at the moment, but that sort of thing is probably inevitable in some form.

I could probably reword a couple rules as part of this proposal, but it is likely that there will be more to follow before this passes (assuming it does), so I refrain from doing so.
