Casting Ember's 4 (Inferno) does not provide shields when using Augur Set mods or Brief Respite. It says energy drain of 0 so it's probably not a bug but working as intended. However, at base 100% efficiency It does say 10 energy/target. Augur set bonus says energy spent on abilities is converted to shields and as long as at least one enemy is hit by inferno energy is being spent.
Since energy drain on Inferno is based off of how many enemies hit, Ember is missing out on a great way to regen shields and reset her shield gate. Even if it's working as intended, I feel that with the addition of shield gating, Ember is being gimped with only one real option to take advantage of these mods. That would be using her 3 (Fire Blast). When you use Fire Blast you lower your Immolation level and that reduces your damage reduction. So, by resetting your shield gate or generating shields you reduce your damage reduction. You lose the effectiveness of your tank ability when you need it most.
Inferno could be really strong at shield regen, if it worked. If you had base efficiency Inferno cost 10 energy/target, hitting 10 targets would give 150 shields. I doubt most Ember's are running base efficiency, since it is difficult to maintain Immolation energy drain without high efficiency. I run 175% efficiency so inferno is 2.5 energy/target. If Brief Respite worked and I hit 10 targets it would regen 37.5 shields. That does not seem like an unreasonably large op number. Seems to be on par with the shield regen of any other frame using Brief Respite when activating their 4th ability.
Wasn't sure if a bug or not so I just posted here instead of bug report section.
