Crown of Vermin

You conjure a cloud of buzzing, swarming insects that emanates from you in a 15-foot radius. Until the spell ends, the cloud moves with you and is centered on you. The cloud has 200 hit points. When you take damage, the cloud of insects protects you by losing hit points and preventing 1 point of damage for each hit point lost. The cloud can prevent up to 50 damage at a time in this manner. If the cloud reaches 0 hit points, the spell ends. If a creature moves into the spell’s area for the first time on its turn or starts its turn there, it takes 25 piercing damage and the cloud loses 25 hit points.

At Higher Levels. When you cast this spell as a tier 2 Epic spell or higher, you increase the hit points of the swarm by 100 per tier above tier 1 and the maximum damage able to be dealt and prevented by the swarm by 25 per tier above tier 1.
