Mining and the reinforced pickaxe

The merchant in the dwarven expedition camp teaches you to clear hard cave-ins that resist a regular pickaxe. You receive a reinforced pickaxe as part of the training. These details come from Fahad Suleman's community walkthrough on Into Indie Games.

The camp is in southern Duskhollow Woods, reached through Caerlin Woods. Check Locations and maps for the route and Quests for hints on getting past the guard.

The walkthrough documents using the reinforced pickaxe in the cave on the way to the fourth obelisk. That does not establish that it opens every cave.

When discussing gold veins later, the author mentions a chisel from the dwarf merchant without explaining how he obtained it. The exact tool needed to mine gold remains unconfirmed; the account does not establish that a reinforced pickaxe is enough.
