About this project

What does Ostrea add?

This mod is based on the bivalve genus. It allows you to find blocks of these mollusks and craft new weapons and items using new recipes, such as pearlization, which can be performed inside oysters. These recipes yield new materials like nacre and pearls. They also provide an alternative way to obtain some existing resources.
