Campfire Cooking in Another World With My Absurd Skill novel omnibus volume 3 was written by Ren Eguchi and illustrated by Masa.

Having conquered the dungeon in Dolan, Mukohda and his three familiars are back to enjoying their carefree adventure! After dodging jealous adventurers and destroying an orc settlement, Mukohda finally arrives at Berléand. There's just one thing to do as they face the ocean—enjoy the bounty of the sea! It’s time to sample kraken and see what the market has to offer. But some meat would also be nice, right...?

After having their fill of fish, the group heads to the dungeon city of Aveling. The gods tell Mukohda that undead wander the dungeon, giving him cold feet. However, they come up with a spectacular gift to encourage him. What—or who—will Mukohda’s party encounter inside?
