Incarnon Evos:
II: Swift Conclusion
III: Swift Deliverance
IV: Deathtrap Trigger

Yes before you mention it im aware it comes off as odd using acuity on a incarnon weapon which sees its form increase the multishot. But beware, the results of this build are shocking to say the least, though we are not taking advantage of the extra multishot provided by the incarnon form we are however focusing on the other main component which is HEADSHOT HOMING.

Due to the fact that this incarnon weapon has multiplicative gun co from [Galvanized Shot], we are able to multiply the quite respectful base damage value of this weapon to the max. using the final incarnon evolution to boost our critical chance and damage we are effectively dealing 351% cc on a whopping 8.3x CD multiplier which will allow you to see numbers upwards of hundreds of millions on this long lost weapon.
