I was thinking about how the Shared XP function spell worked in Dungeoneering. Since you get some xp for tasks your partner does, if you have the requirements. This could be exploited to get the fastest magic experience possible. Since Humidify xp is not reduced you get 65xp/cast. If Shared XP is on, this could result in a greater xp/min than normal high alchemy. However, the problem is that this would require the group to finish the dungeon to obtain cash for ess.
