You don’t HAVE to have Rahyeh’s light and could substitute it for a shield with high Healing Effectiveness (HE). Idea behind the build is you utilize volatile reversal to recover mana and get a nice movement speed boost, spam multiple layers of Consecrated Ground, keep up 4 sigils at all times, and keep attacking with Vengeance. Vengeance use is very important as it allows you to build up fire resist shred on enemies around you, keep ~30% DR buff, and a 100% global damage buff. You want to hit enemies with vengeance every 2 secs or so. Despite the challenges Judgement faces(or perhaps because of them) with its current state I managed to clear 190 Arena waves with it.
Was trying to make the skill strong but I’m not sure it’s possible at this point lol. It does sound like they are making major changes to Judgement so the setup I posted won’t matter much after next patch, but if possible, I will update the build - assuming that the skill still functions somewhat similarly to how it does now.
