Ghostlands: Mana Shifter needs tweaking
npc=16310
Should use Arcane Explosion (spell 29106) when there are enemies nearby, and then use mana drain (spell 29058) until its mana is full and recast arcane explosion once it has full mana. Currently it will use arcane explosion even if you range pull it and there is no one around to suffer any damage from the arcane explosion. It will also use arcane explosion once or twice it seems, after which it keeps using drain mana, even if its mana is full
