## Traits
 
***Hold Breath.*** While out of water, the octopus can hold its breath for 1 hour.
 
***Underwater Camouflage.*** The octopus has advantage on Dexterity ([Stealth](Mechanics/CLI/rules/skills.md#Stealth)) checks made while underwater.
 
***Water Breathing.*** The octopus can breathe only underwater.
 
## Actions
 
***Tentacles.*** *Melee Weapon Attack:* `+5` to hit, reach 15 ft., one target. *Hit:* 10 (`2d6 + 3`) bludgeoning damage. If the target is a creature, it is [grappled](Mechanics/CLI/rules/conditions.md#Grappled) (escape DC 16). Until this grapple ends, the target is [restrained](Mechanics/CLI/rules/conditions.md#Restrained), and the octopus can't use its tentacles on another target.
 
***Ink Cloud (Recharges after a Short or Long Rest).*** A 20-foot-radius cloud of ink extends all around the octopus if it is underwater. The area is heavily obscured for 1 minute, although a significant current can disperse the ink. After releasing the ink, the octopus can use the [Dash](Mechanics/CLI/rules/actions.md#Dash) action as a bonus action.
