The Piercing shard bombs and the shadow shard bombs each have a second option line for a utility status that can actually help a group rather than hurt a group.

Shocking Salt Bomb is the absolute best of the shard bombs in groups as its shock will cancel the shard bomb's outer ring random knockback as well as other pesky forms of knockback. Shock is nice, since it isn't overdone; shock cancels some knockback, while other knockback still occurs.

Seeing that there are no secondary option elemental shard bombs with a utility status to assist groups, I think that the currently existing Deadly Crystal Bomb should receive a fair chance of causing minor shock (other shard bombs have moderate chance).

The elemental bomb does not sacrifice damage for its new status, because the status caused is weaker and it doesn't grant a very high damage bonus against a specific monster family unlike the other secondary option utility-bringing shard bombs.

No nerfing of anything would be necessary since the elemental bomb deserves a small buff (fair chance of moderate shock would be perfect).

What our only DPS-based elemental bomb deserves is a chance to alleviate the randomness of knockback on the outer ring of shards, and a minor shock status would do this perfectly without overpowering the bomb at all.
