Fog cloud

Fog cloud, formerly known as Veridon's cloud, was a conjuration spell that created a fog. A fog cloud could be stored in a small flask known as a vapor bottle.

Effects
It caused a cloud of fog to emanate from the point of origin, obscuring sight and concealing those within. The cloud would dissipate as a normal fog in a strong enough wind, and could not be cast underwater.

Since the spell created air along with the fog, it could be used to renew the air supply of a spelljammer that had spent too long in wildspace. Despite the temporary obscuring effect, the new air created remained even after the spell's duration.

Fog cloud could be cast by druids, sorcerers, wizards, and clerics who commanded the water domain. In the time of Netheril, it could be cast by arcanists of the Inventive and Variation specializations.

Components
The spell required only verbal and somatic components.

History
The spell was created by the arcanist Veridon of Netheril, ruler of the enclave of Lathery. He introduced it in 3375 NY (−484 DR) under the name Veridon's cloud. It later became known simply as fog cloud.

Fog cloud was an uncommon spell in Faerûn in the 1360s DR.
