Ioulaum's longevity

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

Ioulaum's Longevity deals massive damage to every creature within its area (120-feet radius, centered on the spellcaster). Any creature slain by this spell is utterly destroyed as if disintegrated, leaving behind only a trace of fine dust. This spell also extends the caster’s lifespan by 1 year for every living creature it slays.
