Hola!
We have lots of things coming to Hero Siege soonish!
We are removing the gold to rubies conversion for good and will instead give more ruby drops from wormholes.
Rubies can be used to buy mystery chests which can either give you relics, high item level satanics for people over 50 WH (better than what you get from WH), or a bunch of keys or wormhole keys and maybe even hats n stuff! (These can also drop from major bosses with a low percentage).
We will also be welcoming season 1 and the guilds!
