Correction. I meant ArchWizard, not ArchMage. ArchWizard has both poison and teleport, which is very useful in this set up.

A tip to get experience very fast. Pick a map with an absorbing, regenaring monster as end boss. Change your heroes to have this elemental nature that will be absorbed. Have a unit reduce the max hitpoints of this boss by bleeding (cutpurse for example). Use ArchMages to keep the boss from reaching the exit by teleportation and poison it to gain experience (poison/s should stay below 10). As soon as its max hitpoints have been reduced to 1, the experience gain per second will become the poison rate times the experience the boss is worth. Experience for the hero and for the player will come flowing in. I also recommend adding a gentleman to get some extra cash source.
