Forceful Knockback

==Notes==
Forceful Knockback follows the same rules as Knockback. In addition:
* The rules text, 'Double distance', means that the radius of the sector representing scope is twice as long.
* The rules text, 'in any direction', changes Forceful Knockback's scope from a sector to a circle.
* Unlike Knockback, Forceful Knockback is capable of passing through objects (soft collision).
* Forceful Knockback only deals double impact damage when bouncing off objects (hard collision); it deals [50% Offense] damage on soft collision.
* At most, soft collisions can only deal damage, even if the target passes through several objects.
* On soft collision, Forceful Knockback's direction ends with an empty starburst; on hard collision, the starburst is filled with a dot.
* There are objects that Forceful Knockback can break, but cannot pass through.
