Gemspark Blocks

Gemspark Blocks are blocks that glow. The color of the glow depends on the gem used to craft the block. They are also considered mechanisms, as their glow can be toggled by wiring them to a trigger. Gemspark Blocks are crafted from Gems and Glass at a Work Bench.

Gemspark Blocks will also color and add a glowing effect to Waterfalls. This requires hammering a Gemspark Block so that water flows over it. When the Gemspark Block is in its active state, the resulting waterfall will take on the color of the Gemspark block, and will glow for its entire length. Glowing waterfalls do not emit light onto other objects, but merely appear illuminated themselves. Gemspark Blocks will not change the color of Lavafalls or Honey.
