i have the feeling i get to few mithril, i have around 100000 gold but i just dont get all the mithril i need. the mountain sucks up to much of my mithril so i dont get many
Mountain can't suck up mithril. But yeah, in endless mode, especially late endless mode, mithril gets rarer because dens scale off mountain HP so they become exponentially harder to kill, even with maxed ballistae. This will have to be slightly adjusted, or will be naturally improved with new buildings, or ways to attack dens, or get mithril. Late endless mode is kinda a wild west anyway lol.
