Mana vault don't seem to give any more max mana. No difference between zero and 50 mana vaults.
If 2k is max mana, it really does lower the value of mana vaults.
2k is indeed the max mana - we're going to update tooltips of mana-giving aspects to reflect this :)
I admit it, I was just dumb. It gives a nice boost early on consider they not the most gold intensive and a great way to give an advantage for more workers early on.
I did not consider you could sell them later on.
