Order of the Holy Grail: Lots of characters, level up, find gear, every unique item/rarity gives you points for upgrades. It's a super good idle RPG that isn't just another goddamn clicker heroes clone.
The Order of the Holy Grail is quite good. In this game you manage a group of knights and send them to fight in the dungeon. The combat is almost automatic, you can only heal your heroes, leave the dungeon and things like that. Gradually you gain better equipment and level the heroes (also at the beginning you have only 2, at the end of the game you have 13). It's quite addicting.
I have spent a lot of time playing The order of the Holy Grail. You manage a party of heroes.
Tower of Hero is also good.
And if you know a bit of Japanese, then Left could be interesting.
R.O.App tends to make games like that. E.g., The Order of the Holy Grail .
Reminds me of this
