Countess of the Claw's page

Deflating visibly, though still upset, she sinks back into her chair. “I may not be allowed to harm them, but I can still teach them a lesson.”

She weaves her hands about in a sinuous motion, drawing eerie power into them. “Thinking with your tallywhacker is going to get you into trouble, boy. Perhaps you’ll be better off without it.”

She snaps her fingers, and mysterious magic ripples across Stennis's body. Within moments, he has been transformed into a young woman. He stares at his altered figure in disbelief for several seconds, until the Green King calls out to him.

She scowls. “Not forever.”

She shifts again, assuming the form of a young maiden as stunning as the woman to the Green King’s right, though with a face twisted by anger.

“I should kill you for this insult!” she shrieks. Hearing this, Stennis begins to tremble.

And now a quick adventure in the the Plane of Cheese...
- Elf Step also comes into play at Level 9 (1 Action, Step twice) synergizing with Liturgist
- Level 1 Devouring Dark Form is a Morph meaning it can potentially be used while Polymorphed
- 1 Action > Step twice > Sustain both Devouring Dark Form and Darkened Forest Form > Grapple and Change Shape (gaining Temporary HPs)

I would second Ryangwy's Animist suggestion and add that you should also take a look at Devouring Dark Form in addition to Darkened Forest Form. While you won't surpass a Fighter in offense or defense, the Class has a few perks in regards to the Form Vessel Spells.
- Animist has access to Bless, Heroism (also already mentioned by Ryangwy) and Protection Spells
- Liturgist synergizes well with the Form Vessel Spells at 9th level (Leap, Step, or Tumble Through > Sustain Vessel Spell)
- Devouring Dark Form (Sustain > Grapple and later Strike)
- Darkened Forest Form (Sustain > change to a different shape, unless there is a ruling I have missed, I believe you gain the Temporary HPs each time you change to new form)
