So after sniffing around the xmls for a while I managed to make a little set of new tiles which will probably be of interest to a lot of people.
The mod is made of:
1: Massive crystal deposits (pictures), which currently are more common than water in my test attempts (in spite of messing around with rarity all the time), and tend to be unbalancingly clustered. Those deposits can be tapped for a +1 mana regen bonus.

Empire version

Unclaimed

Kingdom version.
2: Mana sifter and mana beacon (empire/kingdom flavor differences) , an expensive building that can only be constructed on level 5 cities (much similar to ereog's tower) which adds +1 mana regen.


Yes those are new particle effects.
I attempted to give the sifters a partial mana regen rate for balance's sake (.25 to be exact), however the game seems to not support such value.
Art-wize they are pretty much finished, with flavor text, new icons and thumbnails, I just didn't add a encyclopedia entry.
It can be downlaoded here.
