Hey, I'm wondering, which do you think would be better; having the spell at the lake backfire, or having him perform the lay-line spell on the way back to Wren's house. I'm getting the odd sensation that Wren wants him to leave right away after the healing spell, but I also vaguely recall Wren telling him he could stay until he's completely healed, which will take another day. So, yeah, it's up to Wren. If he really expects Chall to leave after the lake spell, it's have to be that spell, and if he doesn't mind Chall coming back with him, the lay-line spell would make more sense :P
