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 only difference is that now the druid is equipped with two green bracers. The damage, however, changes a lot becoming 2.5 times higher.

Range

Strategy

  • Not useful to flying enemies at all.
  • If there are a group of enemies that are close together, this tower is recommended since they attack more than one enemy at a time.
  • If there are fast enemies, use reinforcements or barracks to help support Boulder Circle to target at them.
  • This tower has an even larger range than its previous level, so an advanced player shouldn't be hesistate upgrading into this tower.
