Like a rolling stone!


The Boulder Circle is the level 2 Artillery Tower in Kingdom Rush: Origins. It's upgraded from the Stone Circle.

Description[]

"Heavier boulders to crush an even larger area!"

The tower doesn't change much in appearance from the previous one - the druid gains two green bracers and more stones and moss are clustered around him. The damage, however, gets a substantial increase - this tower deals about 2.5 times that of the Stone Circle.

Strategy[]

  • Like all basic artillery towers, the Boulder Circle is good against hordes of weaker enemies but struggles against lone, durable enemies.
  • It cannot attack flying enemies directly, but can hit them with area damage when attacking ground foes directly below them.
  • If there is a group of enemies that are close together, this tower is recommended for its area capability.
  • If there are fast enemies, reinforcements or barracks can be used to block them so that the Boulder Circle has an easier target.
