Your target burns for an additional 5.0% over 9 sec of the total direct damage caused by your Fireball, Fire Blast, Scorch, Pyroblast, Meteor, Phoenix Flames, Cinderstorm, and Flamestrike. If this effect is reapplied, any remaining damage will be added to the new Ignite.
Fire Blast causes your Ignites to spread to 3 nearby enemies.
Ignite cannot critically strike and is unaffected by Haste.
Ignite can spread onto targets who aren't in combat, including neutral targets.
When Ignite spreads, the duplicate Ignite will have the same remaining duration as the original.
When Ignite attempts to spread to a target already affected by Ignite, it checks the other Ignite's remaining damage. If the other Ignite has more damage remaining, the spread will fail; if the other Ignite has less damage remaining, the spreading Ignite will overwrite it.
Patch 9.1.0 (2021-06-29): Fixed an issue that allowed Ignite to spread to targets that could not be hit by spells, such as Rogues under the effect of Cloak of Shadows.
Patch 9.0.1 (2020-10-13): Now causes your Phoenix Flames to spread your Ignites to 8 nearby enemies Ignite no longer spreads to a nearby enemy every 2 seconds. Now learned at level 10 (was 78).
Hotfix (2017-04-10):Fixed a bug where a Fire Mage's Ignite could interact incorrectly with [Duel], resulting in significantly reduced or increased damage to secondary targets.
Hotfix (2016-09-01):Ignite spreading will no longer incorrectly remove other Mages' Ignite.
Ignite's duration increased to 9 seconds, up from 5. Base Mastery reduced to 6% (down from 12%). Level learned reduced to 78, down from 80. Ignite will now spread itself automatically if possible.
Patch 6.0.2 (2014-10-14): Ignite now deals the same total damage with a 1 second period (down from 2 seconds). Base duration changed to 5 seconds so that duration when refreshed remains 6 seconds.
Patch 5.0.4 (2012-08-28): Redesigned into the Fire specialization mastery at level 80 (was a tier 2 Fire talent). Your target burns for an additional X% over 4 sec of the total damage caused by your Fireball, Frostfire Bolt, Inferno Blast, Scorch, and Pyroblast. If this effect is reapplied, any remaining damage will be added to the new Ignite.
Old: Your critical strikes from non-periodic Fire damage spells cause the target to burn for an additional 13/26/40% of your spell's damage over 4 sec.
Patch 4.1.0 (2011-04-26): Ignite is no longer triggered from periodic critical effects.
Patch 4.0.1 (2010-10-12): Ignite is now a 3-point talent (was 5).

No longer limited to one Ignite per target. All mages now get their own Ignite debuff.
Ignite no longer gains stacks from subsequent critical strikes.
Ignite will now reset the DoT duration when reapplied.
Patch 1.12.0 (2006-08-22): The effect of this talent will now still be placed on the victim if the caster is killed before their spell reaches the target.
Patch 1.10.2 (2006-05-03): Bug fix: Should now proc correctly when landing a critical strike with a fire spell.
Patch 1.10.0 (2006-03-28): This talent will now only trigger off fire damage generated by mage spells. In addition, when a fire spell is reflected back at the caster, the caster will now correctly receive the Ignite damage.
Patch 1.6.0 (2005-07-12): Can now be dispelled by any effect that dispels magic effects.
