As is, only 3 enchanted bolts reign supreme. Ruby bolts for taking down large health targets, diamond bolts for high defense ones, and dragonstone for well... anything that doesn't fall onto either of those and isn't a dragon. Excluding pvp, since they have enough issues with balancing, most of the bolt effects need a revisit.
For one, half of the bolt specs don't even work in PvM. Not just insignificant, they literally have zero effect. Topaz and jade, only work on players. Sapphire, no use outside of pking. And pearl bolts? Despite being faction damage, they're worse at their job than the other options.
The solution to this is fairly simple- bolt specs don't need to just be damage. It's a utility on top of their number that enhance your ability, and as such, they can be way more flexible
