Wuthering Waves Aero Erosion Guide: Max 6 Stacks & Top Teams

Aero Erosion racks up stackable DoT—standard 3 stacks, or 6 with Rover Aero. Killer teams? Cartethyia/Ciaccona/Rover. Leaks point to a mid-Dec 2025 Aero spotlight in 2.9. Stack Gusts of Welkin for that juicy 30% DMG amp. (42 words)

Cracking Aero Erosion Mechanics

Picture this: Aero Erosion ticks periodic Aero DMG every 2s, building up to 3 stacks (damage ramps with each one), lasting 15s and refreshing on reapply. Ciaccona's hits or Rover's conversions slap it on—scales off Resonator Level, enemy RES/DEF, and Ciaccona's Outro skill. Rover's Skyfall Severance? It flips Spectro Frazzle or Havoc Bane into 1 Erosion stack; their Outro bumps the cap to 6 for 30s.
Quick tips:

1. Land DMG every 6s per stack.
2. Pop Rover's Outro before your DPS dives in for that 6-stack ceiling.
3. Dial in timing against Aero Predator or Chirpuff—feels off until it clicks.

Gusts of Welkin steals the show here: 2pc nets +10% Aero DMG; 5pc fires off +15% team-wide/+30% personal Aero DMG for 20s once Erosion stacks hit. It edges out Sierra Gale (+30% Aero after Intro, 15s) or Windward Pilgrimage (+10% Crit Rate/+30% Aero for 10s on Erosion hits).

1. Slap 5pc on your main DPS.
2. Keep at least 1 stack alive with Ciaccona.
3. Swap in to proc it on stacked foes.

(Pro tip from the grind: Gusts feels mandatory now—I've swapped half my Aero kits over.)

Elite Aero Erosion Squads

Premium lineup: Cartethyia (Main DPS), Ciaccona (Sub-DPS applicator), Chisa (heal/shield/Havoc shred/Kumokiri DMG). Erosion stacks unlock Cartethyia's bonuses; swap Chisa over Rover from 2.8. Ciaccona piles stacks with hits; Rover variant hits 6-stack Outro and heals via Cloudburst Dance.

3. Cartethyia bursts 'em down.

Solid alt: Ciaccona Main, Cartethyia Sub, Rover. Or Jiyan Heavy DPS with Mortefi Deepen and Rover heal. Erosion focus crushes Jiyan's non-DoT play (Rover overwrites it). F2P dream: Aalto Deepen, Sanhua energy/ATK funnel, Rover.

1. Kit Rover with Rejuvenating Glow 5pc (+15% ATK on heal).
2. Phoebe into Rover swaps Frazzle to Erosion.
3. Hone it on Feilian Beringal Overlord stacks.

Sonata Synergies and Meta Shifts

Gusts shines: +15-30% Aero on Erosion stacks, outpacing Sierra/Windward's blanket buffs (data from current parses). Pairs perfect with Rover conversions + Ciaccona applies feeding Cartethyia bonuses; Iuno's 50% Heavy juices Jiyan.

1. 2pc Aero DMG on every set.
2. Proc 5pc with Erosion uptime/hits.
3. Benchmark against Cyan-Feathered Heron RES shred.

Post-2.7 vibe: Erosion held back by A/B-tier Rover appliers, but Qiuyuan buffs make it future-proof (editor's take: Rover's A-tier Overworld, B-tier endgame—solid but no S yet).

1. Echo farm: Fleurdelys DPS, Bell-Borne heal.
2. Dodge DoT overwrites in hybrids.
