Unimportant (Stone) Pillars are naturally spawning objects found in some rooms of Ancient Pig Ruins or Cave Cleft in the Hamlet DLC. While mining them with a Pickaxe, each hit will cause a brief Earthquake, similar to those naturally occurring in the Caves. After six hits, the Unimportant Pillar will be destroyed, causing an extended earthquake and leaving a useless pile of rock marking where it used to be.
- The player is recommended to prepare a Light Source before mining Unimportant Pillars as there is a chance for hostile Mobs like Scorpions and Rabid Beetles to fall from the ceiling.
- There is no effect to knocking down all of the pillars in a room, despite the quakes and falling debris. Ultimately, the name "Unimportant Pillar" proves accurate.
