Spiral Abyss Floor 12 Breakdown for December 2025
Resets Dec 16, 2025 - runs through Jan 16, 2026. Blessing of the Abyssal Moon? It spits out Swirl shockwaves every 2s—game-changer for grouping.
Chamber 1 kicks off with first-half AoE hell: Recon Log Mek Pneuma (x25), Cryo Cicin Mage (x15), Construction Mek Pneuma (x1). Then flips to single-target Weasels (x2).
Ch2 throws mixed bags: Oprichniki (x1 Fireblade, x2 Line), Kairagi (x1 Thunder and x1 Fiery each), Ruin Guard (x1), Ruin Drake Skywatch (x1).
Ch3? Just the Super-Heavy Landrover (x1) staring you down.
Jump in on the Dec 16 reset. Load Pyro for the upper half Cicins. Plungers like Varesa shine below. Anemo groups 'em up—then cycle Pyro to pop those shields.

Ley Line Disorders: Playing the Buffs Right
First half's 75% Pyro DMG Bonus pairs perfectly with Venti's Pyro-Swirl to melt Cicins—consistent application is key. Second half's 75% Plunging DMG? Four plunges strip those Weasel shields clean.
Venti Swirls Pyro for those every-2s shockwaves; keep Durin or Bennett off-field. Aim for under 20s field time per rotation. Pre-plunge utility first, then Varesa's 4x plunges. Burst right after shields drop.
Chamber 1: First-Half AoE Swarm to Second-Half Weasels
First half: Herd those meks to the center. Pyro shreds Cicins in under 10s thanks to the bonus.
Second half: Trigger the Weasel's kit, then nail it with 4 Varesa or Xiao plunges.
Venti E/Q to group and Swirl. Drop Durin/Bennett Pyro; Fischl Electro if things get sticky. Utility exposes the shields. Follow with Overload or Geo DPS.
Buffget's recharge Primogems got your back—fastest top-ups, sharp rates, secure crypto (USDC) or cards, great after-sales, and server coverage for days.
Chamber 2: Surviving the Mixed Enemy Chaos
Oprichniki Fireblade (x1), Line (x2), Kairagi Dancing Thunder and Fiery Might (x1 each), Ruin Guard (x1), Ruin Drake Skywatch (x1). Pyro-Swirl waves them out in 40s; plunges handle shielded adds.
Anemo/Pyro to clump Oprichniki and Kairagi. Pyro reactions chew through troopers. Hit Ruin weak points or go full AoE. Start with Venti/Durin, Bennett for sustain, Faruzan for Anemo juice.
Chamber 3: Super-Heavy Landrover Boss Beatdown
Super-Heavy Landrover (x1). Stack Pyro Gauge before engaging; Geo + Pneuma (Xilonen/Albedo) paralyzes it. 75% Pyro/Plunge bonuses clear it in 30s. Dodge those delayed slams—timing's everything.
Stack that Pyro Gauge. Geo/Pneuma for paralysis. Shields up during it; burst the vuln phase. Ley Line shockwaves amp your DPS; swap on cooldowns.
