Build a Base and Steal Pets Wiki

Pets are the center of the roll, income, defense, and stealing loop. This page separates confirmed mechanics from the named roster and numeric fields that are not public yet.

Quick answer

What is confirmed about pets

You can roll for rare pets, pets make money even while you are away, and other players can destroy bases and steal pets. That is enough to plan spending and protection, but not enough to publish a named tier list or exact value calculator.

A pet in this game is both an income source and something exposed to multiplayer risk. When you compare pets in the live interface, consider what the game shows about income, how much cash or time it took to obtain the pet, and how difficult it would be to replace after a steal. Do not treat rarity alone as proof of economic value.

Pet data model

Fields worth checking in the current game

These are the useful fields a future pet table should record. Only add a numeric value after it can be tied to this exact experience and a visible checked date.

Name and appearance

Use the exact in-game name and an official or directly observed visual so similar-game pets are not mixed in.

Displayed rarity

Record the label the current game shows; do not convert it to an assumed percentage.

Observed income

Measure what is visible and note the conditions, because pet income or caps may change.

Acquisition path

Separate rolled pets from stolen pets and record the current roll cost only when visible.

Known loop

Roll → earn → protect → raid

1. Roll: spend only from a planned budget using the live cost.
2. Earn: observe pet income rather than copying unsupported rates.
3. Protect: keep a reserve and inspect base exposure.
4. Raid: weigh a target against what your own absence risks.

Withheld claims
