Shattered Pixel Dungeon v3.1 is getting very close to being ready for beta hopefully you'll hear more about it in this coming week. One other new thing in it that I haven't mentioned yet are two new rare enemies! Both are encountered in the Sewers, here one of them: Gnoll Exiles!
Gnoll Exiles are super powerful gnoll scouts, but they aren't as aggressive. Years of solitude has made them pretty shrewd, and they won't pick a fight with you of your allies. Of course they will retaliate, but the extra loot in their backpack might be worth the very tough fight.
