@forecast That is true only if kills count to his experience points instead of the slime's, however it is not a summon nor is he a monster tamer. But a good point I considered as well. Levelinh up the slime is not bad either tho, but I guess he has his reputation as max level sage and his own survival to cosider first... On the other hand a motion sensor might not count at all as an attack like an mouseclick but then the timer should not really work either.
Call me shallow, but if a beautiful, busty young woman dressed in a gym outfit were lying around my bedroom, the only levels I'd be thinking about would concern rigidity & stamina.
NTV sales dick is actually the dungeon master and he duped the dense MC into letting him back into the dungeon, correct? I've seen this coming since he disappeared into the dungeon. Either way, I'd click the mouse button and let the dungeon sort it out.
@Gauvain @Tomba
I was thinking more of a party share exp system though. If they have it or register her as a pet or companion monster so same with party share exp.
