So I was thinking about doing some IL level speedruns but there isn't a rules button to state what the rulings are for upgrading the different disguises to lvl 3 before the next epsiode?

For episodes 1 you wouldn't be able to do this but the rest of the episode you could level up the disguises available in the previous episodes to have them deal more damage.

Will attempt the IL's at some point next month but just wanted to gauge anyone that wants to add their two cents on this.
