Dwarven Gravity Hammer

You know how to effectively hurl yourself like a cannonball directly into your opponents. You Stride twice in a straight line, dealing 4d8 bludgeoning damage to each creature in your path (basic Reflex save against your class or spell DC, whichever is higher). You move until you meet an obstruction or finish Striding twice. The damage increases to 6d8 at level 16 and 8d8 at level 19. Special If you have Dwarven Zero-G Familiarity, enemies have a –2 circumstance penalty to their Reflex saves against your Gravity Hammer in low or zero gravity. You can also Push Off instead of Striding, using a creature in the line to Push Off.
