Elden Ring: Where to find Missionary’s Cookbook 3 and what it unlocks

The Missionary's Cookbook 3 can be found inside the remains of the Smoldering Church in northeast Limgrave by plundering one of the corpses. The Smoldering Church is located between Summonwater Village and the Caelid boundary, slightly off the road. Anastasia, Tarnished-Eater, a formidable Invader who is easy to defeat if you know how guards it.

When you defeat her, you will receive a Furlcalling Finger Remedy and the Sacred Scorpion Charm, as well as the Nomadic Warrior's Cookbook 14 and the Missionary's Cookbook 3.

The Missionary's Cookbook 3 contains exactly one recipe, for Silver-Pickled Fowl Foot, a consumable item that momentarily increases item discovery. Rowa Fruit, Four-Toed Fowl Foot, and Silver Firefly are required for the Silver-Pickled Fowl Foot recipe. You should have little issue obtaining Rowa Fruit because it is the most prevalent crafting item in the game.

Fowl with four toes Foot can be taken from birds, but it's quite rare, so you'll probably have to kill a lot of birds to find one. Guillemots, which look like penguins (except they can fly) and are generally found on coastal cliffs, are more likely to have one than eagles. Guillemots can be found all throughout the island of the Church of Dragon Communion. Silver Fireflies can be found in almost every cave and along the banks of some rivers.
