If you look back he said as long as we refrain from directly casting on his followers :3 We aren't directly casting on them if we're channeling our power through an avatar plus the skeletons and zombies we'll fight aren't his followers are they?
Nor are our stems, or the werewolves, but he hasn't attacked either of them. He also didn't attack the spore fungus, the firejackets, the rosewall, or the corrupted forest.
Because that'd be to easy for him, he wants the challenge, just cause he doesn't attack something doesn't automatically make it part of the deal. You also have to keep in mind that during our battle he became distracted halfway through by the orcs so that could have played a factor in him not using those powers. All in all Maher wants to manipulate us for his entertainment and using his powers directly onto our stuff would make it easy for him to win which defeats the purpose of the entire game he created.
We're bound by the same rules, we break 'em, he smites us all to hell. He has power which is orders of magnitude greater than ours, by the time he had gotten through to the wall he could've demolished the forest ten times over, but he didn't. The orcs only attacked
AFTER he has breached the rose wall. Trying to break the rules will result in our swift demise because he has a lot more in the way of mana.
EDIT: Let's take this into the OOC since it ain't getting anywhere.
