Burning Star (with realistic solar flares!) by ADB created for Version v0.97 (Beta 4)↑
You pretty much have to see this one in action to get the full effect. Look for it in the Burning category.
This mod features an element called Star which flings off sparks and solar flares in a surprisingly realistic manner.
Unlike the Burner element, it emits flame from all sides -- perfect for an omnidirectional heat source.
The power of this mod comes from the Flare element, which is what the Sun emits. Flare would also be really useful for explosive elements that shoot off sparks... is anyone up to the challenge? :)
