Delayed reactions. Prep... doesn't prep mean prepare? If it does, Myron prepared his rune, then kept it dormant until he needed it.

You also overlooked how blood magic was the main factor in Myron locating Corban underground, and he's beyond a master in such an art. Earth magic; I didn't say he couldn't control earth without water, he's fully capable of scouting the area with geomancy. 

You didn't give me access to Myron's space-time paradox, so that's a lie. So no, no 'time' based magic here. Gravity and rift, sure. I never unlocked the timespace paradox. We didn't actually get to that, not yet. I was waiting to be done with this issue. If your character could do what you've expressed him capable of in that post, my god, I'd definitely need to control time itself to beat you.

I assume a prep is actually just an abbreviation of prepare. I should know, my character actually struggles with cast times and spells that require preparation, unlike Corban.
