Hero Spell

Hero Spells are the third major spell in Kingdom Rush: Origins. The spell has different effects depending on the hero you use, resulting in varying cool-down times. Though the Hero Spell can be upgraded in the Hero Room just like any other skill, it can be used immediately in a level without any upgrades. This means each spell has four levels of strength; the initial base plus three additional upgrades.

The Hero Spell is available in Kingdom Rush: Vengeance, however, it has been renamed an Ultimate Skill. It is still upgraded in the same way as other Hero skills.
