Burning Rage

Burning Rage was a generic level 13 Talent that gave heroes a consistent source of AoE damage. The raw damage output is low, but the effect is permanent and hits all enemies around you, so if you think you can survive in the thick of a fight you can burn away the enemy's health bar over time. It is also a very effective choice for increasing your waveclear or against invisible targets, because it instantly breaks them out of stealth when you stand near them, letting you reveal a hidden Nova or one of Zagara's Creep Tumours.

As of October 18th 2020, all instances of original Burning Rage have been modified to unique Hero-specific variations.

Mechanics
Original Burning Rage has radius of 3.5 and ticks once every second. These may vary between modified versions. Damage from Burning Rage type talents is not affected by external damage modifiers or lifesteal effects. It also does not trigger A Call For Help when damaging enemy Heroes under their Structures nor damage neutral Mercenaries before they have been attacked. Burning Rage is inactive while Mounted.
