Dust Bath (Replaces Swarming): When in a sandy/dusty environment a Chinchilla can use dust bath as a standard action. Until end of their next turn any creature in the Chinchillas 10 foot radius receives the following affects: obscures all sight, including darkvision, beyond 5 feet. A creature within 5 feet has 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 wind (11+ mph) disperses the fog in 4 rounds; a strong wind (21+ mph) disperses the fog in 1 round.
