Pyroclast

Pyroclasts are obstacles that appear in Mario + Rabbids Kingdom Battle, primarily in the Lava Pit. They are obstacles that act on their own turn, during the transition between the heroes' and the enemies' own turns; on their turn, they rain fire down onto the battlefield. Where exactly an individual fireball will land cannot be determined, but they will most likely land right where a fireball from the previous turn landed. Additionally, the spots they land on are indicated by black circular marks on the ground so that the player can tell which spots Mario and co. should avoid.
