This is not a build for the bullet attractor, but for the impact of the spear throw. Pick something better for actual results.
I put this together for the fun of it. The idea is to proc a bunch of viral and armor strip with the other procs to make way for [Internal Bleeding] to proc slash and deal decent damage. The galvanized mods should help up the damage the slashes deal. Use [Ash] if you wish for some extra damage.
TL;DR:
1. find a better build to use
2. slap this on anyway
3. shoot fools until the proc bar looks good
4. yeet the freakin' gun
5. pray that it actually does damage
