Propelling Shot

Try a contest of Weapon Skill against the target’s Strength to push the target.
Weapon Skill: Roll to hit instead of rolling a test of skill.
When you use this technique on a Heavy Attack, you may spend 1 more stamina for advantage on this contest of skill.

If you win, you push the target 5 ft., or up to 10 ft. with a Heavy weapon.
For every size bigger than you the target is, it is pushed 5 ft. less.
For every size you are bigger than the target, you may push it an additional 5 ft.
(Sizes: Tiny, Small, Medium, Large, Huge, Giant)

You cannot use other techniques with this attack.

(If the target would be pushed into a mortal hazard which would cause it to instantly or imminently die, such as off a cliff, it gets a health save to avoid being moved into that hazard, but is still moved as far as safely possible.
Being pushed does not provoke attacks of opportunity.)

The DC is 11 for the health save to avoid being moved into a mortal hazard by this ability.

Tip: You can push a creature that is engaging you so that you are no longer within its reach.
