Lost Ark is a free-to-play MMO that was released in Korea (and Russia and Japan) back in 2018, supposedly to considerable success. As you might have guessed from the trailer above, it’s a Diablo-like, in which you pick from of 15 available classes and then plow through swarms of enemies. The MMO aspects manifest via being able to team up with pals to run raids, sail ships and build settlements. All of this takes place in Arkesia, a magic realm overrun by demons upon which players are searching for the titular Lost Ark. Without having burst some demons myself, I can’t tell you much about how its combat differs versus, say, Path Of Exile, but it sounds as if you customise your character by selecting base skills, then level those skills to select upgrades which change their function. There’s also the expected mix of gear and dungeons in which to grind for it.
