The musician's weaknesses lie in PvP. Musicians come at a handful in PvP, which makes it hard for you to be diverse. The only way to be diverse is to build your mercenaries properly. Remember that you must build your team around your debuffs, and what would work well around it. Pick your battles well, and really pinpoint your opponent's weaknesses.And this guide is from the other Atlantica Online website,hope it helps.

Also remember that with DoT, your musician is able to sneak experience points away from your other mercenaries, which makes it hard for them to level. Ravaging Melody can really sap your experience, which can make you vastly outlevel your mercenaries. It's expensive to be a musician because of the upkeep: you have to really let your mercenaries wear the best to let them survive in areas twenty levels higher than they are. It becomes really expensive in the end, so you really have to work at it.

Added to the fact that most starting mercenaries really usually don't work well with your musician;Atlantica Gold the mercenaries you get in the end or while playing are the ones that work rather well with your musician. That doesn't mean you should be discouraged, it just means you really, really have to build well.
