i might have spelling or grammar mistake.... anyway
so you have quest name (another code 1) then
first you need to kill monster called 2 of wallium <--- (I’m not sure about spelling)
it's a boss monster in city 2 area 5 any level.
secondly you will get (another code 2)
you should go to city 2 area 1 you should do 3 star which is very hard level and i suggest go with 2 or 3 people include you because it will increase drop rate.
now (another code 3)
you have to go city 2 area 3 with hard or very hard you just need to clear it.
(another code 4)
this is really easy you just need to talk with girl. she is in city 2 where the near the weapon shop.
From now on you can choose two types (code exotic) or (code architecture)
But you told me about the word is broken so you should becareful. but korean blog shows upper one is code exotic
if you choose one you need to gather something 4 of them you can get these from city 2 area 2 from bet. this one also i suggest go with other people.
last quest of code exotic and code architecture is same so... i hope you choose correct quest....
