Volcano: what comes out by mining
Loot · Volcano · Mine
12 loot lines. The right column is the only one that matters: how many of the game's 30 areas carry the very same line. The longer the bar, the less the trip is worth it.
The 12 lines
Resource Origin Present in Areas
Verdict: all 12 lines are common ground. The area does not yield a single resource that is not yielded elsewhere, not even the rarest one here. This page is the one that should put an end to the legend of the good spot.
The area's 6 activities
The rest of the area's loot, one click away. It is the natural way around this level of the tree: you do not go back up, you move from one activity to the next.
