IDK any RPG phone games. I'm on Clash of Clans and would gladly make an Annihilus Clan (Currently TownHall 8.5?)

If you don't mind text-based, this game works on smartphones, but I generally run it from my laptops browser (I literally have it going 24/7)

It seems like a lot at first, but it's a great incremental/idle/economy/battling game. RPG and MUD features.
I believe a few people from Anni play Use my referral!
