Build Guide
2 of the 3 open slots are for whichever element you want to add to the gun. (Circulation & Enhancement)
The last open slot can be used situation-ally between 3 mods: Fire Rate Up (Self Explanatory probably great with Gley if you aren't reloading) Hit Rate Focus (If you want you accuracy rating back and a little more crit damage) Targeted Vulnerability (Probably best for Bossing for an even more weak point damage).
Make sure to pair your Inversion Reinforcement with the corresponding element you decide to add the weapon.
