- This skill is used by Destroyer Tremor creatures.
- Because the knock down from this skill only affects foes in earshot, it is possible to engage the Destroyer Tremor without getting knocked down by standing on the edge of its danger zone, i.e. the maximum range at which you can activate a targeted ranged skill or use a flatbow/longbow.
