We revisit the vacuum structure of the N = 1 Intriligator-Seiberg-Shenker model on R 3 × S 1 . Guided by the Cardy-like asymptotics of its Romelsberger index, and building on earlier semi-classical results by Poppitz andÜnsal, we argue that previously overlooked non-perturbative effects generate a Higgs-type potential on the classical Coulomb branch of the low-energy effective 3d N = 2 theory. In particular, on part of the Coulomb branch we encounter the first instance of a dynamically-generated quintic monopole superpotential.
