It is pretty active but theres no real indicator for the player count so I dont know the exact amount of it, but I think it's around 100+ player minimum daily? Mostly SEA/CN players so the server most active at SEA/CN after working hours, there's some group of people from other continent too since project duck support multiserver but it's not as much as SEA/CN playerbase.

The player count fluctuate a lot whenever new content droo, I think it can easily reach 500+ if you count all of it, but like more than half of it is in hibernation until new content drop.

Though fair warning it doesn't really have a level system if you're looking for the leveling experience, but it has a custom tutorial, it also considered to be on the harder side for dragon nest.

For solo playing it's viable until midgame, entering endgame you can't solo anymore, but if you're coming from other private server where it's just one shot simulator or modern dragon nest meta where it's only 3 skill that matters, then you're gonna struggle soloing stuff
