Ioulaum's longevity

This spell was developed by the powerful archmage Ioulaum of Netheril to extend his lifespan over the centuries.

Ioulaum's Longevity dealt massive damage to every creature within its area of effect. Any creature slain by this spell was utterly destroyed as if disintegrated, leaving behind only a trace of fine dust. This spell also extended the caster’s lifespan by 1 year for every living creature it slays.
