I won't go into specifics but a bomb that basically shoots eight projectiles. One goes north, one goes northeast, one goes east, one goes southeast, one goes south, one goes southwest, one goes west, and the eighth goes northwest.

Each projectile travels outward to about two times the radius of the current Nitronome, so pretty far.

The purpose of the bomb is to feel like a limited bomb with less coverage but greater overall radius.

With the addition of the tortogun, and swords like Avenger/Faust, Spur, and Wrench Wand, I feel its time for there to be a "hybrid" bomb with niche uses.

Major edit: one of the biggest exploits with shard bombs was "sniping", where the projectiles could reach enemies across long distances. A good thing to do with the shards would be to randomize their path of travel so they won't go "precisely" north, northeast, east, southeast etc. So, for example, the north shard won't go directly north every time, but in more random patterns. This would make sniping feel unrewarding and very slow, instead of just running up to the enemy and quickly decapitating it.

(Plus don't you want your shard bombers to come back???)
