Unleashing rage

"The celestial counterpart of rage is an unformed being made of black miasma which takes the shape of those it inhabits, where its tendrils spread onto those around them. Much like most other celestial and supernatural beings, it is not considered to be evil despite its depiction in the culture. However unwanted in most situations, it is still invoked in in situations where someone needs strength of bullheaded force of will. Communing with this celestial is especially precarious as it is easy for young and weak willed to invoke it and be overwhelmed. With careful invocation and strong willpower those with weaker bodies have been able to perform feats of strength and endurance far beyond their capabilities. Those who are not able to keep a clear mind will find themselves becoming alarmingly tunnel sighted, unable to think straight and impulsive."
