This mod has been conceptualized back in October as dedicated thing for 10th anniversary of Pixel Dungeon becoming free and open source software, but only now I dedicated the time to start making it. The core idea is that I am not the one, who design the features and new items, it's people from community of this game!
A bit Tolkein, but a ring that allows up to 9 other rings be worn, however, the more rings one has, the more curses the one ring applies. Also, if a Remove Curse is used on the one ring, it will destroy a random ring.
Also, could we get a listing of the 20 features so that we don't request something already added?
