Hallo, yeah I just wanted to say that you need to raise your sneak perk to unlock such options

nevermind it turns out the disguise(sneak) option starts appearing once you reach clan level 1, i was confused as there was no information regarding requirements for this trophy on any site so i figured since i found the answer i would share it here

how do you get that option(disguise) to appear? i tried getting into a war state but none of the villages or castles have an option to sneak in so i don't know why it's not working for me
