Supernova Inducer
 

On a strange whim I decided to see what would happen if I replaced the BOMB in the Limited Vacuum Collapser with a NOVA effect.

The result is a weapon that mirrors the power of the Yellow Kawangi, and allows you to gleefully fly around blowing up star systems. The only catch is that if you use it at a system where a nova is already underway, the game will crash (so you can't keep the 30-day nova quest in the game and have this item at the same time).

Probably won't go into Odd Adventures, but it'd be a great item to have in a mod that lets you play as the Kawangi.
