The move keeps forcing the player to go up, even thought Its suppose to go down (?)

As the title says, there Is a move (a tool without a handle) under an NPC, upon activation, the NPC will slash there sword, on contact It will deal damage towards enemies (while making the player and the vicitim rise up) then a final blow, dealing massive about of damage, the problem Is that It keeps forcing the player to go up, and If the vicitim does not die, they stay Idle, but not moving up, help!
