Notes

• This spell and  Trip Attack (Ranged) are the only two sources of an indefinite prone effect. While an enemy can spend movement speed to end the  Prone condition and get up, if it is prevented from moving (e.g. with  Ensnared,  Enwebbed, or  Frightened), it will remain prone indefinitely.
• Along with  Fangs of the Fire Snake (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.

Bugs

• The combat log will incorrectly show the DC calculation as the base DC + Wisdom modifier + proficiency bonus, but the resulting DC will still be based on the higher of the character's Dexterity or Strength modifier.
