A Truthsayer can be hired as a Dogs of War unit. They may be hired by Lizardmen, High Elves, Wood Elves, Dwarfs, Tomb Kings, Empire, Bretonnia (this is an exception to the normal rule), Dogs of War and Orcs & Goblins.

If fighting alongside a Dwarf army containing an Anvil of Doom make two separate pools of Power dice in your own Magic phase: one pool to be used with the Anvil (D6+2 dice) and one to be used by the Truthsayer (two dice plus three for his Level). In your opponent's Magic phase, you can group all your Dispel dice into a single pool.
