A few EGT over limits go all the way to melting out the turbine blades if the fuel is left on for minutes.
in this scenario with no turbine blades left the engine just windmills without exhibiting severe damage symptoms on the way down. The cabin crew will likely call complaining of flame in the tailpipe and after that most cockpit crews will shut off the fuel.
Not a big deal to the flight but damn expensive to repair.
