Coral Hideout is a hideout area unlockable after clearing the hideout of all enemies. It has a beach theme and can be first found in Act 6, The Cavern of Anger after entering through the Southern Forest but before leaving to The Beacon zone.
Coral Hideout first appears as a locked door unable to enter. A switch spawns on a nearby island adjacent to the locked door. Pulling the switch unlocks the door and allows the player to enter the hideout for the first time. After clearing all enemies in the hideout, it becomes unlocked and can be claimed through talking to Helena.
