The Mines are another Player vs. Environment (PvE) activity that players can engage in. To access the mines you need pickaxes, a regenerable resource which you gain 1 of every 12 hours.

The Mine fights can be either to loot runes or to loot gold. Either way, whichever you choose, the fights here are much harder than in Adventure Mode so you have to have decently geared heroes in order to push the mines deeper and deeper.
