Corrupted Greater Kamaitachi

Yokai of the Winds:  All Greater Kamaitachi are found in dust devils 10ft by 10ft.  In this dust devil, they are invisible and all attacks dealt by them are not able to be felt, nor do they bleed.  This means that all damage dealt stacks until the injury is found.  These attacks always hit too.  If a creature has true-sight, they see the Kamaitachi and this ability fails on them

Scythe. Melee Weapon Attack: +20 to hit, reach 10 ft., one target. Hit: 20 (2d12 + 10) slashing damage.

Shape Wind: The Kamaitachi Causes 5 dust devils to appear.   These dust devils can only be dispelled by any sort of pushing back spell or wind spell.  These dust devils move 15 feet toward the nearest enemy of the Kamaitachi and stop.  They move after the turn of the Kamaitachi.  They also deal 10 (2d10) bludgeoning damage when a creature starts its turn in it.  These dust devils are 5ft by 5ft.
