A new update will be coming in the next few days. This update will add a new monster, the Rock Golem, to the game. As of now there can only be female and futanari Rock Golems. There will also be a new item, Rock Motes, added to the game. These will be produced by the Rock Golems, and can be mixed with Elf Fluid to create a random Ore, using the following chance table:

Copper: 55%
Silver: 28%
Gold: 12%
Ruby: 5%

Rock Golems prefer gardens with lots of Soil, Sand, and their favourite, Cobblestone.
