- Prerequisites: Vestigial Arms, Master Rank Alchemy
Your vestigial arms are part of a parasitic twin on your torso, consisting of a head, a torso, and two arms (from the vestigial arm talent). Normally, your twin is mostly recessed within your body, with the visible arms acting like the vestigial arm talent, though you can manifest or hide your twin as a Basic Action. Your twin is helpless, fully subservient to you, and cannot be targeted or harmed. Once per Long Rest, if you succumb to a mental effect that would make you Unconscious, Helpless, or not in control of your own actions (such as Charm, or Paralysis), you can reroll your saving throw; success means your twin absorbs the effect and you can ignore it. Using this ability Sickens you for the duration of the absorbed effect (removing the effect from the twin ends the Sickened condition), and you cannot use your twin’s arms during that time, though passive effects (such as from rings worn on the vestigial arm) continue normally.
