Wychfiend Sersan (CR 11)

This strange extraplanar humanoid has ruddy skin covered in tattoos, green eyes, pointed ears, and a long braided ponytail protruding from the back of her head and down the back of her elaborate robes. Her piercing eyes stare defiantly at you, making you feel uncomfortable.

SPECIAL ABILITIES 

Adapted Body (Ex) 

A wychfiend’s body has adapted to the rigors of planar travel and can breathe in any environment, including the elemental planes, toxic atmospheres, underwater, and even in a vacuum, as if under the constant effects of a necklace of adaptation.

Wyching Bond (Su) 

A wychfiend wychlyn can form a powerful bond with an object from one of the following categories: amulet, bracers, circlet, headband, helm, ring or weapon. This ability otherwise functions as the bonded item ability of the wizard’s arcane bond class feature.  

Wychsteel Affinity (Ex) 

Because of its ethereal nature, some unexplained kinship exists between wychfiends and armor crafted from wychsteel. This mystical connection allows any wychfiend wearing such armor to completely ignore any chance of spell failure normally imposed by the armor. It is for this reason that wychfiends hold wychsteel full plate armor in such high esteem, and will sacrifice their lives to protect or retrieve such armor when it falls into the hands of other races.
