Lots of complex mechanics make them very unreliable. Best use for them is as a melee weapon, at that distance the shards don't spawn and you get 90-105 damage. If you do use for further away then it spawns one shard, that then spawns 4 more, each of which then spawn more 4 and then I think the last ones spawn 8 more. The problem here is that the damage ranges are wild. If all the shard spawns and all of them hit the target you could do anything from 17 to 136. Pic related is from the wiki explaining the shard spawning mechanics.
The fire rate is dependent on if you hold the mouse button or not. Holding it has faster fire rate.
