I'm not 100% sure what the cause is, but from kills the 4x surge only works for a minute or so when you first get your super, but eventually stops giving the 4x surge. Also the 4x surge off of sustained damage has not worked for me a single time, but the super gain off of sustained damage does. I can't confirm, but I think the sustained damage rework is what interrupts the 4x surge from working?
Once it's fixed, I am excited to use it with 4 piece Iron Battalion with all Powerhouse armor to be the Song of Flame champion ;)

Hi there, Thanks for the report! We'll pass this along to the developers for further investigation.

The video is to show that Energy Siphon for super gain and Harmonic Munitions post-super ARE working, but when my super was full I was not getting the 4x weapon surge activating

Solar wasn't proc'ing the x4 surge with full super but the other 2 (I'm guessing all but solar) were behaving as defined by the armour. Could just be a solar thing. Was on prism warlock throughout.

Yeah, I've seen several other reports of this too. I really hope they fix it. I loved Mantle.

Edited by Cyriptik: 6/21/2026 5:12:56 PMhaving the same issue. i had the 4x surge on sustained, but only after i immediately got the super. stopped working like 30 seconds after. Edit: tested and can confirm that if the sustain damage feature activates, it just turns off the surge part of the exotic for the rest of your mission
