As rules state, if i'm not wrong, i can roll every Turn in the States Phases while my trooper is in un a NULL state. This is valid for Dead state too (that is a Null state)? Or since the model is removed from the table Regeneration stop working?
There's no coming back from dead during the game sadly. https://infinitythewiki.com/Dead Cancellation The Dead state is irreversible and cannot be cancelled, unless the rules specific to the mission or scenario being played indicate otherwise. In that case, follow the procedure stated in the rules .
time to write and submit a scenario for the contest :P (just kidding, i don't have time to write a halloween scenario)
