I went to solo the Heliophage with Orendi on Advanced. At some point I noticed that my shields would not recharge anymore - I didnt take damage and I even used Nullify with the immediate recharge helix, but it would not recharge at all.
For more survivability I chose 3 legendary items prior to the match:
It’s the first time I tried the Intermittent Angel. The other’s I used quite a bit and never had any issues, although they might need to be tested.
Would be great if the support could look into it, here’s the match-id if that helps.
Also my Helix:

Edit: Tested without the Intermittend Angel, and Shields recharged normally. Item Bugged?
