[b]PLATFORM[/b]: Steam [b]CPU[/b]: AMD Ryzen 5 3600X [b]GPU[/b]: NVIDIA GeForce RTX 3070 [b]RAM[/b]: 32 GB DDR4 [b]GPU Driver Version[/b]: 552.22 [b]OS Version[/b]: Windows 11 Pro 23H2 22631.3593 [b]ISP Provider/Speed (upload/download) / Connection Type (LAN or wireless)[/b]: Xfinity 1200d/200u LAN [b]DxDiag[/b]: [url=https://pastebin.com/PZF58Vre]pastebin[/url] [b]ISSUE[/b]: The Exotic Machine Gun [b]Deterministic Chaos[/b] appears to be unable to penetrate the [b]non-champion[/b] barriers. It will show the visual effects of barrier penetration from anti-barrier, but it will not register any damage on the enemy itself. These barriers include the Vex Hydra orbital barriers and Phalanx expanding shield. It can be assume this would also extend to Hobgoblin regenerating barrier, Hive Knight black shield, and Lucent Hive Knight permeable towering barricade but are not currently confirmed. [b]REPRO STEPS[/b]: Shoot any non-champion barrier with Deterministic Chaos and watch as there is no penetration. [b]ACTUAL RESULT[/b]: No barrier penetration, no happiness. [b]EXPECTED RESULT[/b]: Barrier penetration with big juicy damage numbers. [b]NOTES[/b]: Deterministic Chaos [b]will[/b] pop champion barriers meaning it is inheriting the Anti-barrier intrinsic but it does not share the ability to penetrate normal barriers as mentioned above. It seems other Anti-barrier options such as Seasonal Artifact modded weapons, other exotic weapons (Wish-Ender, Eriana's Vow, Revision Zero, Arbalest), and even Radiant buffed sources (including abilities) are able to penetrate. [b]Confirmed[/b]: Wish-Ender, Eriana's Vow, Revision Zero, and Arbalest are all working properly against obstructions that they should penetrate. [b]Confirmed[/b]: Radiant buffed sources that are not already gaining some Anti-barrier benefit are also functioning as expected. Update 2: Added a video to showcase the issue in live environment. Update 3: Expanded the context of the issue to include other non-champion barriers. Update 4: Noticed some unusual anti-barrier behavior in the Tym encounter in the Breach seasonal activity where it [i]feels[/i] like anti-barrier efficacy is "intermittent" at range. This may be an mix of aim-assist, recoil, flinch, and aim. Will do further testing.
