How do we make artifact bombs better?

I made a PR that should hopefully address these issues: https://github.com/goonstation/goonstation/pull/3361

Also, I love your ideas, Kamikaze, I might implement this in a future PR.
Especially the ice one. Maybe it could freeze people very close by into statues, cool the air a lot, ice everywhere, sounds pretty neat!
