The official +1 Assassin Leveling description confirms that pets hatch for powerful boosts, but it does not publish names, eggs, rarities, rates, multipliers, or world assignments. The Pet Dex below is therefore a currently documented list, not a claim that every pet has been found.
Currently documented pets
Frog
Repeatedly appeared from early purchases in one current fresh-account recording. Exact boost, rarity, egg name, and hatch probability were not clearly shown.
Checked: October 9, 2026.
Rice Ball
Hatched from a quest-reward egg in one current recording and displayed a reported 5% health boost. Repeatability, rarity, and pool odds remain unknown.
Checked: October 9, 2026.
These two examples come from a single detailed same-game source, so their evidence level is Community reported. Do not infer the total roster, a Frog-only pool, or a guaranteed Rice Ball quest result.
How to add a trustworthy Pet Dex entry
Record the exact name from the live pet card, not from a caption or thumbnail. Capture the egg, shop, quest, boss, or other source on the same run. Add rarity only when the game names it. Record the boost type and value exactly, along with the date and server context.
If the egg panel displays probabilities, preserve the values and the specific egg. If it does not, leave probability blank. Ten pulls are not enough to establish a reliable rate, and duplicate results do not prove that other pets are unavailable.
Use the list to choose pets
Filter mentally by the job you need. For Strength training, look for a pet card that explicitly improves Strength or gain. For boss survival, a verified health effect may be more useful. For drops, do not assume a generic luck effect covers every system.
Compare the new pet with the weakest equipped one. Equip slots are limited, and the official Store lists optional +1 pet equip and +2 pet equip products. Those pass names are official, but their stacking behavior requires a live check.
The Best Pets Guide explains decisions without fabricating a universal tier list. The Hatching Guide covers the reported early shop and quest-egg routes.
Keep the list current
Recheck a pet after an update when its displayed value, source, or rarity changes. Keep the old observation dated rather than silently mixing values from different versions. If two current sources disagree, prioritize the live card and mark the discrepancy.
Do not create a separate page for every name found in a search result. A useful entity entry needs enough detail to help a player locate, obtain, compare, and use the pet. Sparse names belong in this Dex until that evidence exists.
Pet list mistakes
- Calling two observed pets the complete roster.
- Estimating probability from repeated Frogs.
- Assuming every quest egg has the same pool.
- Converting a pet appearance into a rarity guess.
- Ranking a pet without a displayed boost.
- Copying a multiplier from an old video without the card.
- Treating Store luck as proof of better pet odds.
Pet list questions
How many pets are in +1 Assassin Leveling?
No complete official count is public. The list remains “currently documented” until the live egg and inventory displays establish the roster.
Is Frog the only starter pet?
One current run repeatedly received Frogs from the early shop, but that is not enough to prove the pool contains only Frog or to establish its rate.
What does Rice Ball do?
One current run showed a Rice Ball from a quest egg with a 5% health boost. Treat that as a reported observation until independently confirmed in the current version.
Where are hatch rates?
Use probabilities only if the current egg panel displays them. None are published in the official description.
Evidence note
The pet system and boost purpose are Official. Frog, Rice Ball, their reported sources, and the 5% health observation are Community reported from one directly relevant current gameplay source checked October 9, 2026.
