Spirit Burn (Spirit, tier 4, 6,400 souls): 56.3% win rate, bought at 33 min on average. See which heroes buy it most, where it performs best and the builds that use it.
Dealing significant spirit damage to an enemy within 5s causes an explosion dealing damage and a burn to that enemy. While burning, enemies take damage over time and receive reduced healing. The cooldown is per enemy, so each target can only be burned once per cooldown. Deals half-damage on non-heroes.
