Deathlord

Specialty Class

To become a Deathlord, one must first ascend into the Marauder role. Once you have, the Guild of Fighters will ask you to defeat a Demigoth slaver named Minas Taw to secure the release of a noble knight named Sir Falen. Track down Minas Taw along the Southern Boulders border in the Forbidden Lands, defeat him, release the knight, then return to the Guild of Fighters for another quest.
This time, the guild will ask you to defeat an evil Deathlord by the name of General Trajek. Travel to the Vale of Ruin to find Trajek, defeat him and his small army, then return to the Guild of Fighters once more to ascend into the Deathlord role.

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.
