Same issue as you, with a comment from Kabam Rex acknowledging it. It’s apparently something they’re aware of, but no word on if it’s something they consider a bug and are planning to fix yet.
Wouldn’t be too shocked if they didn’t. Kabam’s old content tends to behave very weirdly because it was made before they solidified their terminology and game rules. Abyss and LoL are particularly infamous for it because they were also designed to be extremely hard content and Kabam has never really looked it over and redesigned it like they have for, say, story content. I mean, in your screenshot the Fateseal itself isn’t even working right; if it was, Heimdall wouldn’t have those Fury and True Strike Buffs active alongside it.
Yeah that seems about right about kabam. Thanks for the info.
