Questions players ask
How many pets are there in Build a Base and Steal?
Seven rarity bands (Common → Secret), with three to five named pets per band reported by community trackers. Per-rarity drop rates are not officially published.
What's the best pet in the game?
Secret-tier pets are the rarest and strongest cash/second contributors, but their $/s is not officially documented. The wiki lists every named pet by tier; verify before treating any community post as authoritative.
Do pets have auras?
Aura slots exist on each pet but the aura itself is treated as a placeholder until replayable fun games publishes the aura list. Treat aura effects as unknown.
Can I trade pets?
The launch build does not publish a player-to-player trade route. Pets move between players through the steal loop, not through direct trade.
