It works on barrier champion if you using pulse with pierce mod. However, this weapon MINT RETROGRADE with piercing mod against ads with shield (hydra, minion with front white shield, and Phalanx-cabal). It is not getting through their own shields but only barrier champion works. I test on scout with piercing mod against all enemies with shield. It works and getting through on damages. I don’t understand why Mint Retrograde with piercing mod did not work on them like scout did. I hope you can address this
