Diving Into Luna III Stygian Onslaught Shake-Ups
Quick Patch Rundown
Luna III runs December 10, 2025-January 13, 2026—six diffs, three bosses pushing over 10M HP each on D6. Rewards? 450 Primogems for Diffs 1-3, Dust of Menacing from IV+, and Radiant Phantasm if you clear D6 under 180s. You'll need three teams for Hard III+; co-op matchmaking opens at Hard III.
New faces: Iniquitous Baptist, Battle Hardened Iktomisaurus, and Experimental Field Generator step in for Frostnight Herra, Battle-Hardened Lightkeeper, and Veteran Frost Operative.
D6 HP tops 10M per boss (Luna I had Aeonblight Drake at 14.9M, Fireblade Shock Trooper at 14.9M).
Pro tip: Hit up HoYoLAB for resin checks post-Dec 10; slap on Exalted Ones (those top-16 char buffs for ATK/DEF/HP, live 2h after daily reset).
Why This Hits Different for Casual Clears
Luna III flips the script—Cryo/Hydro/Dendro rotations, dodging Pyro melee, plunging attacks over shields and Bond DoT hell. Top D6 picks? Furina at 90.6%, Arlecchino 89.1%, Ineffa 87.7%.
Ever wiped because of endless regen? Not anymore.
Build three teams around high-usage supports. Farm Dust on Diffs 4-5 (aim for 2 min/boss). Keep an eye on Paimon.moe for overlaps.

Breaking Down the New Boss Tricks
Iniquitous Baptist: Mastering Resonant Watch
Boss cycles Cryo/Hydro/Dendro to amp resistances. Way cleaner than Herra's 50 DMG Gloomveiled nightmare.
Kick off with Cryo applicator. Freeze on Hydro. Bloom with Dendro. Rack up multi-hit Lunar Reactions.
Battle Hardened Iktomisaurus: Cracking Frostbound Resolve
Pyro counters it hard—stay ranged, skip melee. Beats Lightkeeper's Wild Hunt regen hands down.
Position at range. Keep Pyro flowing. Shields up during swaps.
Experimental Field Generator: Tapping Extreme Potential
Plunging attacks shred it. No more 15s regen shields like Operative; Neuvillette (50.6% usage) thrives here.
Plunge your DPS. Jump the telegraphs. Burst right after.
Luna II vs. Luna III: How the Difficulty Curve Shifts
Boss Evolution Snapshot
Luna II threw 50 DMG RES exits, element immunity, HP regen, unbreakable shields, plus Bond/Gleam phases. Luna III? Element rotations, melee/plunging counters, straightforward RES play. Still >10M HP on D6, but clear rates climb—Bennett's at 85.4% usage.
(My take as a longtime guide editor: This feels like Hoyo listened to the salt mines.)
Match your roster to S+ rankings. Co-op Diff 3. Solo Diff 4.
Clear Benchmarks and HP Real Talk
Diffs 4-6 demand 2 min/boss; levels I(40) to VI(110). Luna I D6: Drake 14.9M, Crab 11.3M, Trooper 14.9M. Hit >10M DPS to thrive.
