Ignore Pain An eremite's actions can't be disrupted due to damage or Strikes (such as Attack of Opportunity).

Paralytic Perfection (aura, divine, enchantment, fear, incapacitation, mental, visual) 30 feet. When a creature ends its turn in the aura, it feels compelled to offer pieces of its own flesh to the eremite. The creature must succeed at a DC 40 Will save or become paralyzed for 1 round.

Speed 30 feet, fly 50 feet

Melee [>] jaws +39 (evil, magical), Damage 4d8+19 piercing plus 2d6 persistent bleed and exquisite pain

Evisceration [>] (attack) Requirements The eremite has a creature grabbed; Effect The eremite excises flesh or bone from a creature it has grabbed. The target takes 6d10 persistent bleed damage.

Exquisite Pain An eremite's knowledge of pressure points and pain centers is unsurpassed. A creature hit by an eremite's melee Strikes must succeed at a DC 40 Fortitude save or be stunned 2 (stunned 4 on a critical failure). A creature that critically succeeds is temporarily immune for 24 hours.

Focus Gaze [>] (concentrate, divine, enchantment, fear, mental, visual) The eremite stares at a creature they can see within 30 feet. The creature must immediately attempt a Will save against paralytic perfection. In addition, if the creature was already paralyzed, on a failed save, its unnatural longing causes it to become doomed 1. After attempting this save, the creature is then temporarily immune until the start of the eremite's next turn.

Graft Flesh [>] Requirements The eremite holds a piece of flesh they collected via Evisceration; Effect The eremite attaches the stolen flesh to themself. They either regain 100 Hit Points; reduce the value of their clumsy, drained, enfeebled, or stupefied condition by 3; or reduce the stage of any affliction affecting them by 3.

Shadow Traveler (divine, divination) When an eremite uses plane shift or shadow walk, they arrive at exactly their intended destination.
