Why Neverwinter gold is required in the game?

Alongside a slew of new Neverwinter features added in the game, Neverwinter's return brings players a new world of wonderful dynamic combat and fantasy dungeons and events.

　　For those players who have played this game before, they may be familiar with the whole story; players will be able to create their own quests, zones, and stories of Neverwinter. You may also go it alone, with AI-controlled henchmen, or on of a group of other players.

　　Therefore, you need to buy some Neverwinter gold to help bring you a new adventure through the city from top to bottom and underneath. And also you need some Neverwinter to change them for weapons. Without enough Neverwinter gold, you cannot experience the best skins or magical weapons.
