I beat the skeleton king yesterday without any useful weapon (mithril spear) and being confused alot but it seems that if you try some wands the damage is pretty good once one connects. Undead slaying ammo also works nicely but he has pretty good DV it seems nowadays. Anyway, Executor will make short work of him =)
Treasure Hunter is an absolutely immoral talent and people who take it are slaves of their lust for loot. A real character doesn't rely on worldly goodies to save the world but will do so by trusting his inner strength.
