Benefits package: savior + speeder combination on herd enemies

[Evil Ambassador]

Just now, I ran into a herd of armored numbskulls in Tartarus, who had savior and speeder combination of perks. Every time I managed to land several hits on one of them, he almost instantly went back to four hearts of invulnerability. The auras from about 10 numbskulls allow to keep up the invulnerability almost constantly, and because of their speed I couldn't just separate and focus any single one of them. For the record, I was wielding Exagryph, which is a ranged weapon with the highest base attack speed. Perhaps I could have handled them at a later stage of the run, but in Tartarus my options were extremely limited. I had to give up on a run for the first time in more than a hundred escape attempts.

Maybe there is some synergy between those two perks which causes the invulnerability to be refreshed faster than usual.

Don't get me wrong, I love benefits package because of the tactical challenge that it brings about, and two ranks of this conditions introduce some of the most memorable room fights. However, I feel that any combination of two perks on any enemies that it's allowed on should be manageable at any point where it might be encountered, no matter the weapon or the boon combination. Challenging is fine and welcome, but running into invulnerable groups of foes simply isn't fun.
