Best Deviation Team for Phase 1

Building the right team is essential for conquering Arena Masters. Focus on capturing these three powerhouse Deviations near the Green Field Teleport Tower:

By-the-Wind: Wind-based crowd control specialist that interrupts enemy attacks and manages multiple targets simultaneously. Perfect for controlling battlefield tempo and creating openings.

Polar Jelly: AoE frost damage dealer delivering massive damage across enemy groups. Its freezing effects provide additional crowd control while dealing consistent damage.

Rainman: Strategic support Deviation that summons persistent rainstorms at targeted locations, applying constant pressure and zone control.

This balanced composition handles both single-target bosses and swarm encounters effectively, making it ideal for early and mid-level Arena Masters throughout Phase 1.

Arena Master Strategy Breakdown

Chaos Kitty (Tutorial Fight): This introductory battle teaches core mechanics—summoning Deviations, commanding attacks, and managing cooldowns. Use this opportunity to understand how Deviation abilities synergize before facing tougher opponents.

Flaming Boss (Mid-Level): This flame-engulfed enemy delivers destructive flaming attacks and persistent burn damage over time effects. To survive this fiery encounter, climb to an elevated position where you can avoid ground-based flames while your Deviations attack from strategic angles.

Mr. Wish (Final Boss): Upon reaching Symbiosis Level 1750, you unlock the last Arena Master of Phase 1, Mr. Wish. This fight tests endurance rather than complexity. Deploy your most powerful Deviations and prioritize evasion, as Mr. Wish can eliminate you in just a few hits.

Increasing Symbiosis Level

Your Symbiosis Level determines which Arena Masters you can challenge. The Symbiosis Level cap increased from 5 to 10, with early level progression requiring far less Deviation Value. Memetics now unlock based on Symbiosis Level rather than scenario phase.

Farm Deviation Value by capturing new Deviations, leveling existing ones, and completing Gym challenges throughout the world. Higher Symbiosis Levels unlock stronger Deviations and advanced arena battles.

Unlocking Chaos Trials

Defeating Mr. Wish unlocks Chaos Trials, the final phase of this event. These trials are significantly more difficult than regular arena battles, pitting you against level 60 enemies while your team is capped at level 50. Winning these trials is the only way to obtain Chaos Coins, the true prize of this event.

You can apply the same strategies used against regular Arena Masters to their Chaos variants, but expect tougher resistance and tighter execution requirements.

Pro Tips for Success

Prioritize leveling By-the-Wind first for its versatile crowd control. Save your strongest Deviations for Mr. Wish rather than burning them on easier encounters. Between arena battles, explore the world map to capture additional Deviations—variety provides tactical flexibility for different enemy compositions.

FAQs

Q: Do I need to complete all arenas in order to unlock Mr. Wish?

Focus on consistently leveling your Deviation team and capturing new species to increase your Symbiosis Level efficiently while progressing through earlier arenas.

Q: What rewards can I earn from beating Phase 1 Arena Masters?

Each Arena Master drops progression rewards including Deviation upgrade materials, Symbiosis experience, and exclusive cosmetics.
