Prerequisite: 9th level
You can use an action to concentrate on this power (as if concentrating on a spell). For 1 minute while you maintain concentration, your movement speed cannot be reduced below 5 feet unless you are incapacitated or killed, and you cannot be grappled, restrained, or paralyzed. Once per turn while using this power, you can push a creature 5 feet away from you just by walking into them if they are no more than one size larger than you. Once you use this power, you can’t use it again until you finish a short or long rest.
