So I fought my first Scylla on a haven defense recently. The Scylla had a perk IIRC something like "apex of creation" that granted 25% damage resistance across the board. OK fair enough. What was surprising to me is that this perk can stack itself multiple times. Even with the Scylla marked for death, a full iconoclast shotgun blast on a body part with 0 armor was only doing 180 damage. Fortunately there was only a total of 8 or 9 pandorans on this haven defense. This could have been a very serious problem if there had been more, a situation I will inevitably face in the future. I do appreciate that when I finally disabled one of its body parts it has a massive 200 bleed. But I had to pour on something like 10000 unmodified damage to get there. Unfortunately, the Scylla got away with 400 hp left. I'm left with the impression that there is a way to fight these things and I'm not quite doing this right. In my last unmodded campaign it seemed like during the course of the campaign you fight something something like 2 to 3 dozen of these things. So if you are veteran TFTV player, how do you approach Scylla fights?
