While fighting the Legendary Dredge Mining Suit in the Underground Facility Fractal, it became apparent that his ground-pound attack has no maximum range, and could hit players in the opposite corner of the room and up the stairs.
To be clear, this was not a case of lag. I observed the same results when a teammate moved to the very opposite corner of the room from the boss to resurrect a fallen player. They took full damage from the attack despite being nearly as far away as you can be from the boss during what looks to be (based on the animation) a localized attack. Similarly, I’ve been hit by it while I was on the catwalks and the boss was on ground level.
Since this is the boss’s agony-inducing attack, it seems unintentional that the only way to avoid it is to drop a full bar of endurance into dodging it, especially given the frequency with which he attacks with bombs. Combined with this bug, it seems rather difficult if not impossible to dodge everything. . .
