Iron Taviah
CREATURE 6Female annis hag ritualist
Iron Taviah adds Earthbind, Magic Passage, and Spellwrack to her coven's spells.
Taviah has an old injury that sometimes causes her pain. A physical attack on Taviah that scores a critical hit exacerbates the injury in her wounded leg; in addition to the other effects of the critical hit, Taviah is Stunned 1.
Iron Taviah can take on the appearance of any Medium female humanoid. This doesn't change her Speed, or her attack and damage bonuses with her Strikes, but might change the damage type her Strikes deal (typically to bludgeoning).
The monster changes its shape indefinitely. It can use this action again to return to its natural shape or adopt a new shape. Unless otherwise noted, a monster cannot use Change Shape to appear as a specific individual. Using Change Shape counts as creating a disguise for the Impersonate use of Deception. The monster's transformation automatically defeats Perception DCs to determine whether the creature is a member of the ancestry or creature type into which it transformed, and it gains a +4 status bonus to its Deception DC to prevent others from seeing through its disguise. Change Shape abilities specify what shapes the monster can adopt. The monster doesn't gain any special abilities of the new shape, only its physical form. For example, in each shape, it replaces its normal Speeds and Strikes, and might potentially change its senses or size. Any changes are listed in its stat block.
Iron Taviah has a +2 circumstance bonus to the primary checks to perform a ritual. In addition, she can reduce the number of secondary casters for a ritual by 1. When she does, she must fulfill any requirements for the secondary caster, and she attempts the secondary check normally performed by that secondary caster. She can't replace a secondary caster who is the target of the spell (as in the Atone ritual).
When the characters meet Iron Taviah, the Graveclaw is at the height of its power. As a scattered coven, the Graveclaw grants Taviah the ability to cast the following spells as 3rd-rank occult spells, once per day each, without requiring help from her fellow coven members: Acid Arrow, Curse of Lost Time, Earthbind, Harm, Mimic Undead, Summon Construct, and Water Walk.
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.
