A constant spell affects the monster without the monster needing to cast it, and its duration is unlimited. If a constant spell gets counteracted, the monster can reactivate it by spending the normal spellcasting actions the spell requires.
AC 34; Fort +20, Ref +24, Will +24
HP 238; Resistances force 10
Absorb Force(arcane, force)
Frequency once per round
Trigger A Force Barrage is fired at Usilket, and they are aware of it and have a free hand
Effect Usilket "catches" the missile, absorbing it and causing that hand to glow while it holds this energy. A hand that's holding energy can only be used for Force Bolt. The energy lasts for 6 rounds or until it is released.
Attack of Opportunity
Trigger A creature within the monster's reach uses a manipulate action or a move action, makes a ranged attack, or leaves a square during a move action it's using.
Effect The monster attempts a melee Strike against the triggering creature. If the attack is a critical hit and the trigger was a manipulate action, the monster disrupts that action. This Strike doesn't count toward the monster's multiple attack penalty, and its multiple attack penalty doesn't apply to this Strike.
Usilket makes two Strikes with their fist or with a monk weapon. If both hit the same creature, combine their damage for the purpose of resistances and weaknesses.
Force Bolt
to
Usilket fires two Force Barrage per action spent, dealing 1d4+1 force damage each. They can't spend more actions on this ability than they have free hands. If they use a hand that has Absorbed Force, that hand hurls three missiles instead of two, expending the held energy.
Meditative Therapy(healing)
Frequency once per day
Effect One of Usilket's most unusual abilities is a technique they learned during a long visit to Jalmeray. Usilket enters a trancelike state for 10 minutes, during which they can attempt to remove a disease or one of the following conditions: Clumsy, Drained, Enfeebled, or Stupefied. To remove the disease or condition, Usilket must counteract the disease or condition with a Medicine check. Usilket can attempt to counteract a disease or condition present in another creature, as long as that creature remains adjacent to the witchwyrd during the entire meditation.
Powerful Fists
Usilket's fist Strikes are treated as cold iron and silver and don't take penalties when making lethal attacks.
Grab
Requirements The monster's last action was a successful Strike that lists Grab in its damage entry, or the monster has a creature Grabbed or Restrained
Effect If used after a Strike, the monster attempts to Grapple the creature using the body part it attacked with. This attempt neither applies nor counts toward the creature's multiple attack penalty.
The monster can instead use Grab and choose one creature it's grabbing or restraining with an appendage that has Grab to automatically extend that condition to the end of the monster's next turn.
