Bio Instability

This spell is a part of the Bio Instability spell chain and can be found in the Bio Instability Rune Stone.

When the seniumancer casts this spell, they are unknowingly tapping into a dark power from within their runic soul - a power that feeds on others. The seniumancer is still new to the craft and yet has gotten to know the powers of their affinity of death magic. All the seniumancer knows is that there is a power within them that they can call upon to weaken their enemies. Known as Bio Instability, this decaying magic causes the target to begin to feel sick. They begin to experience slight pains, nausea, and other symptoms that could easily be mistaken as a bad case of food poisoning. What is truly transpiring is that the decay magic is feeding upon them just enough to slow them down. For the duration of the spell they move at half their normal movement rate and must spend their support action vomiting. When the spell finally stops its feeding the target feels the sickness fade away, wondering if it was just something that they ate that has now passed through.
