contents In this article, we introduce the notion of a based action of a fusion category on an algebra. We will build some general theory to motivate our interest in based actions, and then apply this theory to understand based actions of fusion categories on path algebras. Our results demonstrate that a separable idempotent split based action of a fusion category $C$ on a path algebra can be characterized in terms of $C$ module categories and their associated module endofunctors. As a specific application, we fully classify separable idempotent split based actions of the family of fusion categories $\text{PSU}(2)_{p-2}$ on path algebras up to conjugacy.
