“Rods from Honor”
The future of WMDs in the Cosmere is gonna go crazy, we’ve already got split harmonium bombs, will likely soon have light/anti light bombs.
I was thinking though of a non-investiture powered one that is possible already (assuming one could soulcast tungsten/another dense material).
Theoretically if a soulcaster, were to soulcast and tungsten rod, then a Windrunner could send it into space via lashing and just let it drop on its own. Or even better potentially, as it would require less stormlight, the Windrunner could fly the soulcaster up and then soulcast it in space.
