Coastal Cave is a dungeon in Elden Ring’s West Limgrave area, with some Demi-Human enemies as well as a twin boss fight. There is also a secret passage leading to a new area. In this Elden Ring Waypoint Ruins guide we’ll tell you how to find the dungeon, defeat the bosses, what loot you can expect, and the new area accessible through the cave.
Coastal Cave location and enemies
Coastal Cave is in West Limgrave, directly east of the starting area. You may want to purchase a torch from Merchant Kalé for 200 Runes in the Church of Elleh for some extra light.
There are various crafting materials throughout the cave, including Cave Moss and a Land Octopus Ovary. The cave is full of Demi-Humans. Being stealthy will prevent these enemies from calling to alert one another. Sneaking past or defeating all the enemies before entering the boss room will make the fight much easier, as you won’t have alerted the bosses to your presence in advance.
Coastal Cave Demi-Human Chief boss fight
Just outside the boss door there is a golden summon sign which summons the NPC Old Knight Istvan, who can be very useful in this fight.
After entering the boss room, you can continue to crouch through the long grass to take out some of the smaller Demi-Humans as well as potentially getting a sneak attack on the sleeping Demi-Human Chief.
If they were previously alerted, they will already both be attacking you, making the fight much more difficult. Entering from stealth should allow you to fight them one at a time, making the whole fight much easier.
After defeat, the bosses will drop Tailoring Tools, which allow you to customize your armor from sites of grace. They will also drop the Sewing Needle. The NPC Boc will ask for this item.
Coastal Cave secret passage
After defeating the bosses, instead of using the warp back to the entrance, continue ahead down the corridor. Watch out for more Demi-Humans.
You will emerge onto an island to the southwest of the main coast. At the top of the hill on this island is the Church of Dragon Communion site of grace. You can purchase various dragon-themed incantations at the shrine here.
