The use of galaxy clusters as cosmological probes often relies on understanding the properties and evolution of ICM . However, the ICM is a complex plasma, regularly stirred by mergers and feedback, with non-negligible bulk and turbulent motions and a non-thermal pressure component, making it difficult to construct a coherent and comprehensive picture. To this end, we use the FABLE simulations to investigate how the hydrostatic mass bias is affected by cluster dynamical state, mergers, AGN feedback and turbulence over cosmic time. We also look at how this links to the evolution of chemo-thermodynamic cluster profiles, compared to observations and other simulations.
