Such a wasted potential. Typical of korean gacha games, aggressive monetization.
Great & superb character l2d+cg art, nice pixelated old school environment. But thats it. To max a char, need 5 dupes (costumes). So if there's multiple costumes, welp, tough luck for f2p.
Weapon gacha, screw the korean devs for implementing this. It's suck that you need to pull weapon gacha with premium currency, the status on those weapons are also randomized. So if you're f2p and you got lucky, pulled an exclusive weapon for dps char but lo & behold, the fixed status are HP instead of ATK or crit/dmg.
