Can nonstabiliserness be generated from stabiliser states simply by coupling them to a heat bath? We explore the thermodynamic limits of nonstabiliserness under minimal assumptions and derive a necessary and sufficient condition for when such a process can create it from an initial stabiliser state. This provides an analytic characterisation of the nonstabiliser states that are reachable in this way, together with quantitative bounds on their degree of nonstabiliserness. Our framework also identifies optimal regimes, specifying Hamiltonians that maximise nonstabiliserness generation and the critical temperatures at which it emerges.
