Hero's Ark

https://herosark.com/

Hero's Ark is a free-to-play fantasy MMORPG you play straight in your browser — no download, no install. Roll one of 7 classes (Warrior, Mage, Cleric, Necromancer, Paladin, Ranger, Rogue), pick from 21 specializations and 18 races, and set out across a persistent open world. Grind and gather with real crafting professions, delve dungeons and take down world bosses, and team up in parties and guilds with shared banks. The endgame is kingdom warfare: claim territory, build and upgrade your holdings, raise armies and generals, and fight other players for control of the realm. Prefer to progress hands-off? Auto-battle keeps your hero earning while you're away. Play on desktop or on the go with the companion mobile app. Free to play — jump in at herosark.com.
