Master Conjuror

Master Conjuror was a warlock talent in the Demonology tree.

History
Firestones and Spellstones were previously equipped in the wand slot and before that in the off-hand slot. The Spellstone gave the user an improved critical strike chance and could be used to dispel magical debuffs. The Firestone (item) gave bonus fire damage to the weapon of the user (only for melee strikes) and also granted a damage bonus to all fire spells cast by the warlock.
