Saturn is one of the Mythical Devil Fruits in Haze Seas, and it stands out because it skips the whole awakening grind. There are no special materials to farm, no superboss to summon, and no Poneglyph trip. Every move, including its transformation, opens up simply by raising the fruit’s mastery.
Quick answer: Reach 125 mastery on Saturn to unlock Spider Transform (E), which permanently grants the Spider Human Hybrid form and its second moveset. Everything before that unlocks at 0, 25, 50, and 75 mastery.
How to get the Saturn Fruit
Saturn is a Mythical fruit, so it is rare on both fronts. You can buy it directly from Cynthia, the Fruit Dealer, for 500,000 Beli or 2,999 Robux. If you would rather wait for a natural roll, be prepared for a long chase. Saturn’s spawn rate sits at 0.0015%, which makes it one of the least common fruits in the game.
You can play Haze Seas and reach Cynthia through the official Roblox listing.
Saturn base moveset and mastery thresholds
Before you transform, Saturn gives you five standard abilities. The first one is free the moment you equip the fruit, and the rest unlock at fixed mastery points. Each move is tied to a specific key.
| Move (Key) | Mastery required |
|---|---|
| Poisonous Slashes (Z) | 0 |
| Spider Barrage (X) | 25 |
| Spider Cull (C) | 50 |
| Spatial Annihilation (V) | 75 |
| Spider Transform (E) | 125 |
The unlock at 125 mastery is the one to aim for. Spider Transform (E) is what flips Saturn into its Spider Human Hybrid form and opens the second half of its kit.
Spider Hybrid form moveset
Once Spider Transform is active, your character enters the Spider Human Hybrid form and swaps to a full second set of abilities. Because the transformation is unlocked permanently through mastery, you never have to re-earn it or farm anything to keep it.
| Move (Key) | Mastery required |
|---|---|
| Whiplash (Z) | 0 |
| Hyper Leap (F) | 0 |
| Phantom Strike (X) | 25 |
| Dreadful Storm (C) | 50 |
| Saturn’s Ring (V) | 75 |
| Spider Transform (E) | 125 |
You will know the unlock worked when the E prompt for Spider Transform appears and pressing it switches your moveset to Whiplash, Phantom Strike, Dreadful Storm, and Saturn’s Ring. The Dreadful Storm plus Saturn’s Ring pairing is the fruit’s main damage combo for ground control.
How to raise Saturn mastery fast
Mastery is item-specific, so all of your progress comes from actually using Saturn in combat. Different targets hand out very different amounts of mastery EXP, which is why what you fight matters more than how long you fight.
| Source | Mastery EXP |
|---|---|
| M1s (basic hits) | 0.1 |
| Skills | 1 |
| NPCs | 2 |
| Bosses | 10 |
| Superbosses | 150 |
Bosses and superbosses are dramatically faster than clearing small enemies, since one superboss is worth 150 EXP against 0.1 for a plain hit. There is one catch. If a target is more than 200 levels above you, you only earn 0.2x EXP from it, so fight enemies near your own level for the best return.
A few other things speed the climb. Completing quests that pay out Mastery EXP, farming high-level enemies for steady kills, and timing your grind around the 2x Fruit Mastery events that Haze Studios runs during major updates and weekends all stack up quickly.
Tip: Mastery caps at 500, and every 2 mastery adds +1 to Saturn’s combat stat, up to a maximum of 250 points. So even after you have every move at 125, pushing further keeps raising your damage.
Why Saturn skips awakening
Fruits like Dragon and Electricity gate their strongest forms behind 300+ mastery and a specific superboss material that you have to farm at the Poneglyph. Saturn works differently. Its transformation is baked into the mastery track, so there is no material to hunt and no awakening quest to finish.
That makes Saturn one of the most direct Mythical fruits to fully unlock. You commit to leveling it, hit 125 mastery for the Spider Hybrid form, and keep grinding toward the 500 cap for the stat boost. For anyone who wants heavy PvE damage and a full two-form kit without the usual awakening RNG, Saturn is about as clean as high-tier progression gets in Haze Seas.
