You must try to find the song at some point in the final game of Lost Ark
It's not the end of the world in the event that you fail to catch one here as well, however it might be a good idea to dedicate certain Lost Ark Gold sessions to acquiring the most Pirate Coins as possible so that you don't need to be concerned about earning lesser amounts of them here and there during normal play.You will also discover Pirate Coins while fishing, however, the rewards from this game aren't guaranteed and it doesn't appear to be a great way to game to manipulate the RNG system. As such, I wouldn't suggest prioritizing that particular activity over another unless you have a reason to concentrate on fishing, for whatever reason.
It's entirely up to you to decide what it is you want to spend the hard earned Pirate Coins on, but there's a minimum particular item to be found in Pirate Coins that many players will wish to get at some point The Song of Resonance.
The very unique track will set you back 16,500 Pirate Coins, which probably seems like a lot (that's because it is quite a lot) but it's well worthwhile considering that the song will unlock important specific locations and goals. You can purchase the Song of Resonance from Treasure Hunter Igran in Peyto the ship that is located in the waters to the west of Anikka north of Pleccia, in the east and west of Vern. You must try to find the song at some point in the final game of Lost Ark.
You can be fooled early into thinking North Vern is a largely empty continent from Lost Ark. It's an initial succession of towns and villages with plenty of intrigue but very little action. But once you get past cheapest Lost Ark Gold, things and we're talking monsters - start to get real.While Paladins typically go into Raids at Lost Ark as support, providing buffs, shields, and heals but in Chaos Dungeons they can absolutely take on the game with the right strategy.
