After the fight has finish, the effect will return to its previous level. How long it takes to get going or return, how much effect it has, I don't know. Haven't had much time to test it out, and that might take a good chunk of time. We might never find out.<br/><br/>He might also have other effects that come into effect as his ability increases.<br/><br/>As for it being unheard of, I had theorized it before, and the constructs ran some simulations, and agreed that, while uncommon at least, an anti-mage would be a magic predator, and a good adaptation. And while I was wandering, I encountered either others with the ability, or evidence of them."
