Shadow Knights are a durable tank class. This Warrior/Necromancerhybrid has vampiric and damage-over-time spells. Shadow Knights have the unique ability to Harm Touch (do direct damage) every 72 minutes, the power of which increases in absolute terms but decreases relative to enemies' hit points as a player levels up. Since this class is a hybrid, they must wait longer than the Necromancer to begin receiving spells, and longer yet for the more potent incantations such as Summon Corpse and Feign Death. In most cases the level difference in spell acquirement is +25-30 levels. For example a Necromancer might learn a certain spell at level 4 that a Shadow Knight is unable to learn until level 34. Eventually - Shadow Knights are able to summon a weak skeleton pet, summon players' corpses who are in the same zone as them, and cast the spell feign death, similar to the monk's feign death skill. The feign death spell allows the Shadow Knight to function as a "puller" for a group when successfully casting the spell allowing them to clear their agro list by pretending they are dead. Their necromantic abilities give them great power over the undead, making them able to do more damage to those opponents.
Shadow Knights are required to worship an evil god: Bertoxxulous, Innoruuk, or Cazic-Thule. Because of this, they generally have faction problems in good cities regardless of race. (Rallos Zek is a deity choice for Ogres only.)
