Hi Sarah!
Just letting you know that we have just released a big update to Rogue Summoner.
We added a new set of items (Magic Rings) that will give you (or your monsters) passive abilities!
We also implemented Power Rocks: they will be found randomly throughout the dungeons and will change the dynamic of part of the board (like giving you discounts to place monsters on certain spots (or make them more expensive!), buffing (or nerfing) the monsters in the effect area, and other cool behaviors.
You will be able to find some of these new mechanics on the "Army Of The Dead" dungeon in the demo (and more so in the full game!).
Thanks again for suggesting that we added more mechanics to the game, I think these were awesome additions (and we still have more cool systems coming up!).
Cheers!
