There are a total of four volcanic altars in Dredge, and players need to sacrifice various different fish creatures at the altars to activate them, thereby summoning the Outer Gods. Since the volcanic altar is a mid-game quest node, its importance in the game cannot be underestimated. In this article, I will specifically introduce the locations of the four volcanic altars in the game for your reference, hoping that this content can help you~

If players want to start the challenge mission of the volcanic altar, they must first complete the main storyline of Sturay Bay, and then head to the Devil's Spine. When heading to the Devil's Spine, players will receive a prompt that due to the mixed energy ahead, the player feels danger and cannot enter. At this point, the volcanic altar mission officially begins.
The four altars of the volcano are located in Greater Marrow, Gair Cliff, Sturay Bay, and Winding Straits. In Greater Marrow, the location of the volcanic altar is actually at the J9 position, and players can find it by following the marked points. The offering required for the Greater Marrow altar is five sturgeons, and after successfully completing the sacrifice, players can obtain an important in-game item, the Warp Thread Spindle.

The volcanic altar at Gair Cliff is located at the P3 position. When making the offering, players should ensure their backpack already contains the Decorative Crab and Stone Crab. After successfully sacrificing them, players can obtain the Abyssal Maw. If players have not caught these two marine creatures through the capture function, they can actually go directly to the seafood market to buy them and then use them as offerings.

The volcanic altar in Sturay Bay is to the northeast, and players can find it by marking H2. The offering conditions for the Sturay Bay altar are quite strict, requiring players to offer four different types of sharks. Sharks are relatively difficult to catch in the game, so it is recommended that players activate the Sturay Bay altar later in the game. However, the reward for this offering is more generous: the Flesh-Toned Crane.
The altar in the Winding Straits is located at D13. If you can't find the D13 position, stand under the eastern watchtower and look west; you should be able to find the flashing marker. For this offering, players need to sacrifice a mutated fish, and the reward is the Robust Fishing Rod.

The above content is all about the locations of the volcanic altars in Dredge. In these altars, players need to complete four puzzle tasks and collect the required fish to unlock them. The overall process is quite lengthy. I hope that after reading this content, everyone can go into the game and experience it for themselves~
