Burnt will slowly lose their health, similarly to poison. However, burning units cannot be cured of their burns, apart from by garrisoning. Burns will also wear off automatically outside of the castle.
A unit can be burned and poisoned at the same time. Like poison, a yellowish red flame will appear above a unit's health bar to indicate that it has been burned.
Units that can Burn
Below are the seven units in the game that can burn, listed in order of Empire.
- Archidon (Fire Arrows researched)
- Albowtross (Blazing Bolts researched)
- Magikill (Blast spell) (AoE)
- Bomber (AoE)
- Infernos (Basic Attack) / (Fire Rain) (AoE)
Burning has become incredibly useful since Patch 1.89, when it was introduced. This has made many units more deadly than before: for instance, the Magikill's Blast spell has become much more potent since it was since pre-1.89, as well as Bombers' explosions, Archidons' Fire Arrows and Albowtross with Blazing Bolts. This is one of the main threats posed by Elemental players as well: the Fire Elemental, Charrog and Infernos all cause Burn damage, which allow these units to wreck havoc on enemies if used correctly.
Units that can inflict Burn or Burn-causing AOE spells have thus become extremely potent ways of killing lower-health units especially on relatively longer maps: its uncurability renders it as a sure-fire way of massacring units with about or less than one bar of health, or at least putting them temporarily out of action as they have to garrison and heal.
