and I'm pretty certain that he's also a god of fire.
He is a god of earth, war and creation
And we will add all that stuff like uberweapons later, when we upgrade fortress, now nukes are just not needed, it's an airbase with some fire support, not a strat bomber . Now we decide what to ask from Uristel, he can't make a chaos cannon
Again, be more practical and concentrate on more important and urgent matters then some cannon that may ( or may not) be useful much later
I doubt that this mole will be useful alone, if we want to mine ourself with any non laughable pace, we'll need an army of them... And magical roots can penetrate roots just like magical moles can
GWG, tunnels in stone have other reasons to collapse, and you trust an animal to make it right. Tunnels of the real world moles collapse constantly, not only when it's raining. It's why holes in the fields appear. Expect the same holes from our magical mole. IMO, You all overplayed DF and think that mining is easy.
As for worshipers, it's true, but expanding and improving afterlife first is an easier way to increase mana generation...
Sap miners... plant miners and undeground, don't you see a problem?
Save mana for the fortress construction? we have 300+ already
