You become untouchable for a period of time, as an unbreakable spiritual wall. This is an active semblance, Warden, and thus grants you some unique abilities.

Passively, you have +1 to your hit points per level, you gain +1 to your constitution score, and have +1 to your AC passively.

Actively, you can spend 4 aura charges as a bonus action to become nearly invincible, becoming immune to all slashing, piercing, and bludgeoning damage, along with resistance to acid, cold, fire, lightning, poison, and thunder damage. This effect lasts for 1 minute, and afterward, you must wait 12 seconds (or 2 rounds) before you can use it again.
