In Atlantica, winning a battle with at least two mercenaries in the unavailable status for the Strategist title means going to the formation window and unchecking one of the boxes for two of your mercenaries so they are 'ghosted out' during the battle and you can't use them. It does not mean the mercenary has to be unconscious.
Persuading residents for the Linguistic Genius title means convincing the wandering residents to go to your Atlantica Gold. You get a certain number of people for each of the wandering residents you convince, usually between 50 and 200 Atlantica Gold for people. You cannot do this quest unless your guild owns a town.
Currently, with the servers occasionally going down at random times, there's a strange bug where if you haven't completed a quest yet, you lose the things you had counted towards the completion for a certain period of time. It's almost a roll-back, but only for quests. These quests are affected by it, so be warned. You do not lose items. Here is Atlantica powerleveling service at low price.
