Wychfiend Ovarch (General, CR 18)

This strange extraplanar humanoid has ruddy skin covered in tattoos, green eyes, pointed ears, and a long braided ponytail protruding from the back of his sleek great helm. His 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. 
Dimensional Shift (Su) Wychfiends can teleport to a nearby space as a swift action as if using dimension door. This movement does not 
   provoke an attack of opportunity. The wychfiend must be able to see the space that he is moving into. He cannot take other creatures with 
   him when he uses this ability (except for familiars). A wychfiend can move 5 feet for every two Hit Dice or class levels he possesses 
   (minimum 5 feet). A wychfiend can use this ability a number of times per day equal to 3 + his Charisma modifier. 
Wyching Bond (Su) Due to their otherworldly nature, a wychfiend can form a special magical bond with an item of the appropriate type, 
   dependent upon the wychfiend’s career path. The wyching bond of those who choose a full caster level arcane spellcasting path is similar to 
   the wizard’s arcane bond class feature. The wyching bond of those who select a more militant path is similar to the paladin’s divine bond 
   class feature, but only applies to the wychfiend’s weapon or armor (see the Divine Bond alternate class feature of the Divine Defender 
   paladin archetype in the Advanced Player’s Guide) and is not divine in nature, but arcane, and draws upon the wyching energies innate to
   the wychfiend. 
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.
