We revisit the construction of the duality group for \(\mathcal{N}\) = 2 \({\widehat{A}}_{n}\) -shaped quivers SCFTs and generalize it to the previously unexplored case of \({\widehat{D}}_{n}\) -shaped quivers. We then provide a systematic description of non-invertible duality symmetries in both classes. Furthermore, we characterize the \(\mathcal{N}\) = 1 mass deformations of these theories that preserve such symmetries, thereby identifying a large class of \(\mathcal{N}\) = 1 SCFTs with non-invertible duality symmetries inherited from their parent \(\mathcal{N}\) = 2 theories.
