A: As a rule, campaign missions do not give legendary items, with the exception of the random Fortune Box, which does have a chance for legendary. So basically it’s not a specific level, it’s a chance to get a fortune box. The chance to get a fortune box rises a little if you play a mission on a higher difficulty. - Dev Jonny
Q1a: Does the chance of obtaining the Fortune Box only depend on difficulty or also on the level in campaing ?
Q1b: For example - is the chance of getting the Fortune Box from the last Boss on normal difficulty higher than from the first Boss on insane ?
Q2: Is the chance of getting legendary from the Fortune Box always the same or it also depends on mission difficulty ?
