Eisen the Mine City is the stop for some advanced equipment and crafting legendary weapons and armors.
Getting to Eisen:
- From Hot Spring Town, head north to North Mountain 1 and then take the right path to North Mountain 4. Continue heading north past the marsh and the plateau.
- The Foothills have signs to Eisen which point in the opposite direction. Heading North West will lead to the Elven Forest that is East of Surglane Village but turns you around just like from the Surglane Village side.
