Fling
From Gempunks
When you fling a creature, you forcefully move it some direction up to a specified distance. Flinging a creature vertically is harder than flinging one horizontally, so every meter of vertical movement costs 4 meters.
When flung directly against an object, the creature takes damage as per falling a distance equal to the maximum vertical distance you could have flung that creature.
When flung, a creature must make a DC 5 Agility check or fall prone.
Flinging a grappled or riding creature breaks them out of the grapple or, if they end up not on the creature, stop riding. A ridden creature brings along any creatures riding it.
