Karkerheart Luvkur

Karkerheart Luvkur is a Brainrot God-tier brainrot in Steal a Brainrot, the Roblox collection-and-trading game where every pet generates passive income and can be upgraded with mutations and traits. At base, Karkerheart Luvkur earns $297.5K/s and costs $67.5M from the in-game shop — those numbers are the floor, before any multiplier from mutations or trait stacking is applied.

It is obtained via Getting from Heart Lucky Block in-game. Verify availability before any trade — Steal a Brainrot regularly cycles which items are obtainable, and a brainrot's market value can swing sharply when the game flips it to limited or unobtainable status.

Across live Eldorado marketplace listings, Karkerheart Luvkur prices currently range from $0.2 for the Gold variant up to $0.2 for Gold. Mutation multipliers compound on the base income, so the same Karkerheart Luvkur body at a higher-tier mutation out-earns its Default variant by exactly that ratio per second.

For trade evaluation, divide the USD value by your offer's value to get a clean ratio. The trade calculator does this automatically and applies trait amplifiers (Brilliant, Sniper, etc.) which add to base income additively rather than multiplicatively. See the methodology page for how the valuation algorithm actually computes these numbers, or the trade-valuation guide for a step-by-step walkthrough.
