Pedia special Rain of Fire

Rain of Fire is the second of the two major spells in Kingdom Rush and Kingdom Rush: Frontiers. When used, a red targeting icon will appear on the map, and once selected it rains down several meteors on the ground, causing area-of-effect True Damage to both ground and flying enemies. It is useful for eliminating small hordes of enemies, and acts well as a last-minute lifesaver. However, its long cooldown time (80 seconds) somewhat reduces its effectiveness.

Initially, it starts with three meteors, but additional upgrades will increase its damage, explosion radius and meteor count, and leave behind burning ground that deals physical damage to survivors of the initial attack.

In Kingdom Rush: Origins, Rain of Fire is replaced by Thunderbolt, which serves the same function as a spell that deals area-of-effect True Damage on a long cooldown.

Statistics

The unit of Scorched Earth damage is per secondmeteor.

Each meteor creates its own burning effect on the ground.

Actually, each level-4 upgrade increases only 66% in Scorched Earth damage.
