Solar Fragment Block

Every fragment you turn into building material is a fragment not going into endgame gear, and running the Solar Pillar again for decoration is a long way to go for a wall. Finish your armor and weapons first, then come back and build.

What you get is a block that lights itself. That is the real reason to use it: a room walled in these needs no torches and no lanterns breaking up the surface. The red and orange tone reads as heat, so it suits forges, lava rooms and anything meant to look hostile. There is no matching wall, so pick your backdrop from something else before you commit.
