Spawn cadence

Public servers spawn The Prototype every 3-5 hours; private servers every 30 minutes. Manual spawn costs 485 Robux (15-min cooldown). The Prototype despawns 40 minutes after spawn.

Mastery ranking

First Place (killing blow) = 13% mastery. Second Place (damage contribution) = 10%. Third+ = 0%. Alternate ranking: top 3 by contribution gets 13% / 10% / 5%.

Warp Portal pity

Warp Portal drops at 7% base chance. Pity counter increases chance by +3% per missed kill, so consistent farming guarantees the drop over time.

Best characters for farming

Use the Prototype Farm tool to plan spawns around quest cooldowns. Mastered characters with high Ultimate damage are the fastest killers.
