I haven't played Cabal in a while and I was browsing to see what new features were added and I saw that you can summon mercenaries in dungeons to help fight for you for about 15 min or till death, but I was wondering how you get Mercenary cards, and is there any way to get specific mercenary cards, and if so how?
BTW...If you obtain a card, is it limited to one summon per card(then gone after the summon) or is it a permanent item once collected?
