Marble

Marble is an item added in the A Little Rain Must Fall update. It is obtained by mining Marble Pillars, Marble Trees, Harp Statues, and Maxwell Statues with a Pickaxe or Pick/Axe, or by using the Touch Stone, which drops 2 Marble, 2 Rocks and 1 Nightmare Fuel (upon its use). It is used to make Checkerboard Flooring and a Marble Suit.

Marble has the potential to fall during an earthquake, turning it into an unreliably renewable resource.
