the caves are pretty comfy and easy, until you get dogpiled(pfft) by a bunch of cultists. Silver armor and some healing potions are recommended to power through the worst case fights.

Fortunately silver is relatively pretty easy to harvest. Hunt around for a vein, dig under it, and pop it all at once for the dopamine rush. The bonus of digging deep is that it keeps most of the enemy spawns away, trying to dig from the surface can lead to nasty ambushes.
