Hi everyone, thanks for all the feedback. This update fixes a bunch of things you told us about.
Mana pills
Natural mana regen was way too low, so your team kept drinking pills nonstop and a thousand of them could be gone in a few minutes. Mana now regenerates 1.5% of max mana per second (it used to be 0.1%), so normal idling barely needs mana pills anymore.
Selling gems
The Sell tab in the city shop now lists your unsocketed gems along with your gear. Tick them together and sell in one go, or use the Gems button to select all of them at once. Gems socketed in your equipment are never sold.
Other fixes
We also retuned Maps 2 to 5: the first floors of each new map are easier to push, while floors 200 and 250 are a tougher finish. Map 1 is not harder than before.
Keep the feedback coming in the community, we read all of it.
