Conceal Temporal Anomaly

The caster splits the flow of time around a temporal disturbance. This reduces the turbulence it causes and shields it from magical detection. A detect temporal anomaly spell (or an item with the same effect) has a chance to detect the hidden effect, but the base chance is lowered to 25%. Other detection spells (true seeing, detect invisibility, and so on) also have a 25% chance to detect the anomaly, but those uninitiated in the mysteries of chronomancy are unlikely to know what it is they are seeing.

Vortices can be hidden in this way, but the forces involved become extremely hazardous. A chronomancer must check against Wisdom at - 4. Failure destroys the vortex, ages the caster 1d20 years, and reduces the caster's Wisdom permanently by 1 point.

The material component is a glass bulb filled with the blood of a vortex spider. This spell cannot be used cumulatively with itself.

Notes: Restricted to chronomancers; common.
