Deathspike
When taking falling damage; you can elect to fall with a weapon impaling your target and reducing your fall damage while causing massive damage to your target. Make an attack roll as normal; but if you hit you may do additional damage; roll falling damage as normal; but any 5 OR 6 results instead do damage to your target with the same base type as your weapon and these results in no damage to you. Eg you deathspike down 30'; attacking a guard at the gate; you hit and roll 6D6 for falling damage; rolling 1,2,3,4,5,6. You do an additional 11(5+6) points of damage to your target and take 10HP (1+2+3+4) of damage from the fall. You can elect to attack a wall like this; arresting your fall. You can elect to allow others to do this (Shooting them from a catapult; kicking someone off a wall); but they only do damage on 6's and take -4 to hit.
