Cosmic Being F Move unlock explained
Finding Cosmic Being at Sea 2 (Punch Island)
Before diving into the grind, make sure you already have the Cosmic Being fighting style unlocked, as it is a strict prerequisite.
Without it, none of the progression counts. Once ready, head over to Sea 2 – Punch Island, where you’ll find the Cosmic Being Master NPC, who essentially acts as your progression checkpoint.
It’s worth preparing a strong loadout and possibly gathering a team beforehand, because every requirement favors efficiency through cooperation rather than solo play.
Requirement 1: Defeat Cosmic Being 15 times
Travel to Punch Island in Sea 2 and locate the Cosmic Being Boss spawn. The boss appears every 30 minutes, which is the biggest bottleneck if approached passively.
Fight alongside other players. The boss has high HP, so teaming up ensures faster kills and reduces the risk of failure. Repeat until you reach 15 total defeats. Keep track of your progress, as consistency is key here.
The combination of server hopping and group combat is the most efficient strategy, allowing you to complete this requirement far quicker than intended pacing.
Requirement 2: Reach Floor 90+ in Infinite Tower 5 times
Head to Tower Island in Sea 1 and enter the Infinite Tower mode. This is a separate challenge focused on endurance. Push through enemies until you reach Floor 91. This is the required milestone per run.
Complete this process five times. Each run counts individually, so consistency matters. Form a team to speed up each run. With multiple players, clearing waves becomes significantly faster and safer.
Requirement 3: Equip Astral Bloodline
Acquire a Bloodline Stone through farming, trading, or events. This is the key item needed for unlocking. Use the Bloodline Stone and roll for the Astral Bloodline. RNG plays a role here, so patience may be required.
Once all three requirements are completed, the Cosmic Being F Move unlocks automatically!
Rewards of the Cosmic Being F Move
What stands out in this unlock process is how much it rewards smart play over raw time investment. Server hopping eliminates downtime, while team-based farming multiplies your efficiency across every requirement. If you try to complete everything solo and passively, the grind can feel unnecessarily long.
| Reward | Effect |
|---|---|
| Cosmic Being F Move | Unlocks automatically after requirements |
| Damage Boost | +30% increased damage |
| Combat Advantage | Stronger PvE and boss efficiency |
Once all requirements are complete, the move unlocks automatically without needing additional interaction, making it a satisfying payoff for your effort.
By contrast, actively optimizing your approach turns a multi-day grind into something you can realistically finish in a much shorter window.
Unlocking the Cosmic Being F Move in Sailor Piece is a clear example of how preparation and strategy can reshape your experience. You’re not just grinding—you’re optimizing every step to get a meaningful combat upgrade faster. With a +30% damage boost, this move becomes a core part of your build, especially if you rely on high-damage abilities.
If you stay consistent, use server hopping wisely, and team up whenever possible, you’ll unlock this ability far quicker than most players expect.
