ACTION
Activity 2 actions

Requirements You are not observed by any enemies

Effect You phase yourself into the interstices, veiling yourself from physical reality. You become Concealed. You can use this concealment to Hide or Sneak as your disassociation from reality makes you difficult to focus on. If you use a hostile action, this effect ends after the action is complete; otherwise, it lasts for 1 minute.
