Masteries in Pet Simulator 99 are long-term skill tracks for systems you repeat: hatching, breaking, upgrading, opening rewards, fishing, digging, fusing, shopping, and using boosts. The best first target depends on what you already do most, because each mastery gains XP from a specific activity and pays off with different permanent perks.

Mastery group
Core farming and hatching
These masteries grow from the loops most players repeat every session: breaking objects, opening eggs, and converting pets. They are usually the easiest to progress naturally if you farm or hatch for long stretches.
Breakables Mastery
Activity Farming • Best For Long farming sessions and loot grinding
Breakables Mastery rewards the core PS99 loop of smashing objects for coins, diamonds, and drops. It is one of the easiest masteries to progress while you are already farming.
- XP source
- Break objects in normal areas
- Notable Perks
- Better loot, faster respawns, longer flags, and mini-chest bonuses
- level 99
- +100% respawn speed,
- +21 flag slots,
- +50% mini-chest spawn chance, 2x flag duration, 5x mini-chest loot, plus Breakables Mastery Cape
- Grind Style
- Natural AFK or active farming grind
- Shortcut Note
- Usually worth leveling through normal farming unless you need the final loot perks quickly.
Eggs Mastery
Activity Hatching • Best For Players who hatch constantly or chase pet variants
Eggs Mastery is built for players who spend long sessions hatching. Its best perks reduce hatch friction and make large hatch sessions cheaper and faster.
- XP source
- Open eggs
- Notable Perks
- Cheaper eggs, faster hatch animation, bonus egg slots, and golden/rainbow hatch chances
- level 99
- +5 bonus egg slots, 30% cheaper eggs, and Eggs Mastery Cape

Pets Mastery
Activity Pet progression • Best For Players converting, fusing, or enrolling large pet stacks
Pets Mastery improves the systems that turn pet stacks into stronger or more useful pets. It overlaps with Fuse Mastery because fusing pets can train both tracks.
- XP source
- Use the Gold Machine, Rainbow Machine, Fuse Machine, or Daycare
- Notable Perks
- Faster machines, better gold/rainbow chances, lower pet requirements, and better Daycare rewards
- level 99
- -2 pets required for golding and rainbowing, 2x Daycare speed and diamond loot, plus Pets Mastery Cape

Minigame and machine grinds
These masteries need focused actions instead of general farming. Fishing, Digging, and Fuse can be worth pushing when you enjoy that loop or want the specific machine or minigame rewards.
Fishing Mastery

Fishing Mastery is a focused minigame track. It does not train from every fishing-like activity, so the source minigames matter.

- Notable Perks
- Faster casting and catching, Deep Pool access, better Deep Pool Huge chance, larger bobber, and rainbow rod chance
- level 99
- +50% chance to catch a Huge from Deep Pools, 2x rainbow rod conversion chance, plus Fishing Mastery Cape

- Focused minigame grind
- Shortcut Note
- Good shortcut candidate if you dislike fishing but want Deep Pool perks.

- XP source
- Dig in the Digsite-style minigame route
- Notable Perks
- Better Digsite chest drops, more diamonds, better chest find odds, Mastery Chest access, Huge chance, and rainbow shovel chance

How mastery unlocks and levels
Mastery unlocks at Rebirth 4 and appears as the pink-star skill system in your inventory. Each mastery has its own XP source. Hatching eggs trains Eggs Mastery, upgrading enchants trains Enchants Mastery, using Boost Exchange trains Boost Exchange Mastery, and so on. Grinding the wrong activity will not move the mastery you meant to level.
Level 99 is the cap for each mastery, but the useful rewards start before that. Many tracks add discounts, speed boosts, tier access, automation, better odds, or stronger loot at mid and late milestones. That is why the best first mastery is usually the one tied to your main routine, not a universal top pick.
How to choose a first mastery target
Start with the activity you repeat most. Heavy hatchers get the clearest long-term value from Eggs Mastery. Players who run potion or enchant upgrades should care about Potions or Enchants Mastery because those perks reduce friction and open higher-tier use. Long farming sessions make Breakables Mastery easier to level naturally. Fishing, Digging, Fuse, Keys, Gifts, Economy, Superior Chests, and Boost Exchange are better when you already use that specific route.
Shortcut items should be saved for a mastery you either value highly or dislike grinding. A Mastery XP Potion gives direct XP to a chosen mastery, while an Ultra Mastery XP Potion instantly maxes a chosen mastery. Those items are too useful to spend only because a row sounds important. Match the shortcut to the activity you want to avoid or the perk package you will actually use.
What level 99 capes mean
Every mastery can unlock its own level 99 mastery cape. Those normal mastery capes are cosmetic and should not be treated as the main reward unless you care about collecting them. The separate Master Skill Cape is different: it comes from maxing every current mastery and grants a diamond earn bonus. It is an all-masteries completion reward, not a fifteenth mastery row.
How to Use This Pet Simulator 99 Mastery List
XP source tells you the exact action that trains the mastery. Best for explains which kind of player gets the most value from that track. Notable perks summarizes the permanent bonuses without dumping every milestone. Level 99 names the final practical reward and cape note. Shortcut potion advice belongs in the row notes and FAQ when a mastery needs extra caution.
FAQ
How many masteries are in Pet Simulator 99?
There are 14 mastery skills in this list. The Master Skill Cape is an all-masteries reward, so it is not counted as a mastery row.
When do you unlock Mastery in Pet Simulator 99?
Mastery unlocks at Rebirth 4. After that, the mastery screen appears as the pink-star skill system in your inventory.
Which Pet Simulator 99 mastery should I grind first?
Pick the mastery tied to the activity you already repeat most. Eggs is best for heavy hatchers, Breakables fits long farming sessions, Potions and Enchants fit upgrade-heavy players, and minigame masteries are better when you actually play those minigames.
Does every level 99 mastery cape give a boost?
No. Normal mastery capes are cosmetic. The Master Skill Cape is the special all-masteries reward and is the one tied to a diamond earn bonus.
Should I use an Ultra Mastery XP Potion right away?
Only if you know which mastery you want to skip. Use it on a track with perks you will use often or a grind you strongly dislike, not just the first mastery that is low level.
