Warlock

Specialty Class

To become a Warlock, you must first ascend to the Battlemage class. Once you’ve done so, the Guild of Mages will ask you to travel to Skuldoon to help Shaman Feros Duul. When you reach Feros Duul, he will request that you enter the Forbidden Lands and obtain the Cursed Idol from Laerok Maa. After completing this task, you have one last quest to complete to obtain the rank of Warlock.
For your final task, the guild sends you to the Vale of Ruin in search of an evil Warlock named Glavenmaur. This warlock is assembling a small army and must be stopped! Destroy Glavenmaur, then return to the guild to ascend into the Warlock class.

Installation: Dungeon Lords

For the original game (not the MMXII version), in order to earn advanced classes from base class onward, you will have to join one of four guilds in Dungeon Lords. When you join it, you’ll add the first tier adept class to your character (unless that was the class you selected at character creation). All four guilds work about the same. For each one, you’ll have to go on an initiation quest, then you’ll be given a second tier class quest, then you’ll be given a guild quest, and then you’ll be given a third tier class quest. You can join two guilds in the game, but you can only select one third tier class for your character, so try to plan out your advancement before selecting any quests.
