Rallos Zek the Warlord is a level seventy monster in Drunder, Fortress of Zek (also called the Plane of Tactics). In order to spawn him, you must first kill Rallos Zek. He appears to be Rallos Zek the Warlord, but he is not! He stands in the same pop area. Once you get Rallos Zek to 60% health, he tends to despawn unless you kill him first. After Rallos Zek has despawned, Rallos Zek the Warlod will pop.
Rallos Zek the Warlord drops
All drops might not be known! The Gods of Everquest tend to vary on their loot. Feel free to let me know if you know of any other drops!
