First; equip holy resistant armor, predator armor works. Second: your first loadout should be a greatsword (Caserjaw great sword works well.) and the arcane damage charm. Relentlessly assault the judge. The other two should leap at you when you walk in, giving you time to blitz her down. After this, switch to layout two: Great Hammer and Impen Charm. Depending on your luck and spacing, the two remaining will either both leap at you at once, allowing you to hit both. That can be baited out by running away. If that doesn't work, simply just get one hit in and dodge the other.
