How to beat Aurora
Aurora is the final threshold boss, and she’s built to punish slow or unoptimized teams. While it’s technically possible to defeat her with a high-investment, non-DoT team, the fight is designed to favor Damage-over-Time (DoT) strategies, especially for players without maxed-out SSRs in red gear. The fight revolves around a stacking system of Accumulated Anger and Wrath, with Aurora unleashing increasingly powerful AoE attacks based on how many Wrath stacks she has. Your goal is to slow Wrath buildup by removing Accumulated Anger stacks through either multi-hit attacks or DoT procs, making speed and efficiency the name of the game.
Aurora’s Skill 2 is the core of her kit. It applies Wild Proclamation, a debuff that acts like a DoT but can be cleansed or prevented with immunity. It also applies Curse Shield, which blocks healing equal to 25% of your max HP—and this cannot be blocked by immunity. On top of that, she gains 20 stacks of Accumulated Anger when casting, which later converts into Wrath. If Wrath hits 16 , she instantly uses her Skill 3, an AoE nuke that scales harder with each use. Because her side adds grant her Wrath passively each turn and are nearly unkillable, the best method is to ignore them and focus on bursting Aurora down with debuffs and DoTs.
The most effective strategy is to bring a team built around buff removal, DoT application, and speed control. A comp like RC-77, Kazami, Obol, Fangus, and Rin works wonders: RC-77 brings ATK/DEF Down and multi-hit utility; Kazami removes immunity and speeds up your team while reducing cooldowns; Obol and Fangus stack consistent DoTs, with Fangues also applying Speed Down to control Wrath gain; and Rin adds shields and defense boosts to keep your team alive. This setup keeps Aurora’s Wrath in check and avoids most of her lethal retaliation effects while wearing her down safely over time.
If you don’t have the right DoT heroes built, you can bring a traditional comp with nukers like Massiah and Tiamat, backed by supports like Lingluo, DokiDoki and RC-77—but be warned: this route demands tight cooldown management and top-tier gear. Expect long runs (up to 9 minutes), and little room for error. Ultimately, while both methods can work, DoT builds offer a much more reliable, accessible, and strategic path to victory, especially when dealing with Aurora’s immunity cycling and scaling AoE nukes.
