Wraith lords are one of my favorite summons, precisely because they are so hard to kill. Protection 21, Defense 16, and MR 17. My advice is to use armor-piercing weapons or armor-negating spells (such as Astral Weapon). If you use spells, it'll help to have penetration boosters to overcome their high MR.

EDIT: as Taqwus suggested, Incinerate is probably your best choice.
