Notes
- This spell and are the only two sources of an indefinite prone effect. While an enemy can spend movement speed to end the condition and get up, if it is prevented from moving (e.g. with , , or ), it will remain prone indefinitely.
- Along with (which uses an unarmed attack roll), this is the only other Way of Four Elements abilities that scales with Strength or Dexterity rather than Wisdom.
- Since this uses weapon action DC, Heightened Manoeuvre from the
Gauntlets of the Warmaster will apply. Conversely, bonuses to spell save DC such as Lay Bare Their Weakness from the
Hat of Uninhibited Kushigo will not apply.
