Core Kit Mechanics

Mesmerized Mark System: Applies marks that detonate for 500% ATK Physical damage (12s duration). Anomaly triggers guarantee crits with +50% CRIT DMG for 12s.

Fever State: Builds stacks granting up to 1000 ATK bonus based on initial ATK at max stacks.

Key meta factors:

• Angels of Delusion expands with Aria (S-Rank Ether Anomaly) and Nangong Yu (Physical Stunner)

Common Mistakes

Build Errors

Neglecting Energy Regen: Need 130-150% total. Secure through Slot 5 + W-Engine before damage stats.

Wrong W-Engine: ATK-focused without Energy Regen causes rotation failures. Minimum 50% Energy Regen required.

Suboptimal Main Stats: ATK% on Slot 4 outperforms CRIT for Fever scaling and mark damage.

Team Composition Pitfalls

Breaking Faction Bonuses: Replacing faction members reduces performance 10-15%.

No Stunner: Wastes +30% Stun DMG Multiplier and creates inconsistent detonations.

Energy Competition: Pair with energy solutions through W-Engines/Drive Discs.

Faction Misunderstandings

Partial Faction Teams: Need three members—two provides zero bonuses.

Ignoring Bangboo Alignment: Non-faction Bangboos lose 5-10% synergy.

Advanced Tips

Micro-Optimization

Animation Cancel: Cancel EX Special at 0.8s after mark application, saving 0.3-0.5s per cycle.

Buff Snapshot: Activate DPS Ultimates immediately after Sunna's buff application for maximum ATK capture.

Energy Threshold: Maintain exactly 60 Energy, not 100+. Excess wastes passive value.

Content Adjustments

Shiyu Defense: Compressed 12-15s rotations for speed bonuses over sustained damage.

Deadly Assault: Maximize Fever stacks for 15-20% higher sustained output.

Exploration: Minimize field time, rely on off-field energy regen.

Hidden Tech

Mark Inheritance: Marks persist through stun transitions—pre-apply before stun activates.

Fever Preservation: Stacks decay slowly, allowing 2-3s swaps without loss.

M4 Energy Refund: 40 Energy every 180s creates rotation flexibility.
