Just did a Havok map where we fought the “Karnak twins” -ish double boss and got a DH spawn on us from a Heinous Rituals ahead we never knew about (also vent purge), because we didn’t get a ritual progress bar.
It’s always been an issue with more than two boss health bars, making the third invisible, but with the new Heinous Rituals mutators another solution should probably be sought.
Either they show up and get squished, or they spawn while you fight a bunch of monsters and a waves, which so far always ended up in us getting an express delivery back to the Loading Star.
They can be easily done if u have high dps team. Because if their shield is gone they can be killed (they dont have dmg activation shield as captains have).
