Melf's minute meteors

Melf's minute meteors was a fire-based evocation spell.

Effects
The spell created six tiny meteors that orbited the caster for up to 10 minutes, until released upon a target or until the caster stopped concentrating. When released, the meteors exploded on impact.

The effects of Melf's minute meteors could also be achieved by accident through the misuse of opals as components of magical items that evoked both fire and lightning.

Components
The spell needed somatic and verbal components, as well as niter, sulfur and a bead of pine tar for materials.
