Currently gearing an Ignite Fireball Sorc and I have the Dragon Mage, Dragon Breath, and Mirror Breath nodes fully allocated and am using the Plasma Ball node in the Fireball tree to give it the lightning tag so that it will activate Dragon Mage and Dragon Breath. When I cast Fireball with my character sheet pulled up I can see my fire damage goes up by 100% for Dragon Mage, but my ignite chance does not change at all even though I should be activating Dragon Breath as well.
Does anyone know if Dragon Breath is bugged, or perhaps the character sheet tooltip is simply not updating to reflect the increase to ignite chance?
