Nyx

Nyx/Nox
Nyx is an optional boss in chapter 4 and as most of the enemies the player already faced, she is enchanted.

She is Razorbear chimera, and nothing much is known about her.

The player can meet her in two possible  places, depending on which route the player took in chapter  3. The player can meet her at the entrance of Grand Ziggurat if they took Nefris path,  or in the Warden's office if they  took secret passage route.

Personality
She is  dual persona. Her personalities are:

Nyx
Very shy and clumsy, while enchanted it's her  who is in  possession of  main  body

Nox
Straightforward, foulmouthed, but  honest at  the same time. While enchantment she posses their  snake  tail. She helps Soriel at the  beginning of  the  fight, to  be later scolded by Nyx

Appearance
She is a chimera, made from different animals, so  her looks  depend  on them. She has reptile like green eyes and fair brown hair. She has bear ears  and  paws  with  sharp metal  claws, and a snake as a tail. She has scales on  her legs and neck which continues towards her face.

Battle abilities
She's a really tough enemy, because of her ability to switch her element depending on what attack she used, this is both her strength and weakness

Caustic Venom : Water-type attack and debuff that makes you take more physical damage.

Razor claws : Metal-type physical attack that deals more damage if under the Caustic Venom debuff.

Chain Lightning : Lightning type magical attack, very powerful and hard hitting, may one shot the player if not careful.
