The inky cloud created by this spell billows out from your location. The cloud obscures all sight, including Darkvision, beyond 5 feet. A creature within 5 feet has one-half concealment (attacks have a 20% miss chance). Creatures farther away have total concealment (50% miss chance, and the attacker can’t use sight to locate the target).

• A moderate current (11+ mph) disperses the cloud in 4 rounds; a strong current (21+ mph) disperses the cloud in 1 round.
• The spell functions only underwater.

Material Component: A small vial containing the ink of a squid or octopus.
