You Shall Not Pass

You Shall Not Pass [Combat]

Yours is the spear that shall not break the line that shall be held.
Prerequisites: 6th level
Benefit: Once per [Encounter], as a swift action, you may double your [Melee] range for two [Rounds]. You then may create a spread with a radius of your [Melee] range originating from you as a [Binding] effect that moves with you and lasts for two [Rounds]. For each opponent, the first time each [Round] that opponent enters or exits a square within this spread, it must stop moving. A successful Reflex save (DC 10 + 1/2 character level + KDM) allows the opponent to continue moving, but it suffers a penalty equal to half its movement speed to its movement speed for that movement.
