Has anyone else run into this little gem?
1) 5th level necromancer has corpses
2) Casts animate dead on them
3) Orders them to attack him.
4) Slays his own undead for xp.
5) Rinse and repeat
6) Profit to level 20
Also works with conjuration spells, perhaps even better because you can get more xp out of higher level creatures.
Yea and buying ladders for 5gp and sawing them in two, so you can sell the two resulting ten foot poles for 10gp each. Rinse and repeat and you be richer than King Midas.
