War Witch

Specialty Class

To become a War Witch, you must first ascend into the role of a Enchantress or Valkyrie. Once you have completed the requirements for either of these classes, the Sisterhood will ask you to free Sister Talya from an evil warrior named Kaugris. Travel to the Forbidden Lands, defeat Kaugris to set Sister Talya free, then return to the guild for your final quest.
For your final task, the Sisterhood will tell you about a dread witch named Greuvenia the Pox who is summoning an army of monsters within the Vale of Ruin. Travel to the vale, defeat the witch and her abominations, then return to the guild to ascend into the War Witch 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.
