Aclyone

Abilities: 

Nacht Maelstrom: A dark aura looms overhead and rains down a storm of thin crystals. The energy coating the crystals saps the target's energy, transferring it to Aclyone. The thin crystals coat the ground in a radius around Aclyone, making the ground difficult and hazardous terrain. Stepping on the crystals will trigger an energy sap.

Stone Spear: Large, stone spears rise from the ground, cloaked in shifting tenuous shadows. The spears jut up from the ground and cover a large area. The dark energy deal additional damage. Most spears are as large as young trees (10-12 inches thick and 8-10 feet tall). Mostly in groups of 5-10 spears per round. 

Hell Mouth: The earth buckles beneath your feet as shadows rise up from the cracks. The shadows grip onto whatever they can feel give off energy or is seen as a threat to the user. The more someone struggles, the harder the grip becomes. The shadows can also lash out and cause bludgeoning damage. Shadows typically act on their own accord unless given instruction.

Shape shift: Through unnatural means, Aclyone can shift her form into a humanoid shape. The transition is obviously wrong and distorted. 

Alignment: Nochmal (obviously)

Personality: Stern. No bullshit. Once upon a time, when she could afford to, she was more joking and kind. However, time, anger, and her dedication to Yaga has hardened her. Her conviction now drives her to the finish. In her more humanoid form, she finds herself smiling more than she is used to. It reminds her of a time when things were new and surprising. 

Background: She is usually secretive about where she comes from, but what is known is that she first came into contact with Yaga when she was young. Being an ocean dwelling knochen, she is able to go into deeper water, closer to where Yaga is contained. Because of this, her affinity with Yaga is strong. Because of the long exposure to Yaga's influence, her appearance and personality have changed dramatically.
