Palworld Breeding Calculator: How the CombiRank System Works
Breeding in Palworld is driven by a hidden stat called CombiRank (also known as Breeding Power). Every Pal in the game has a unique CombiRank value — the rarer and more powerful a Pal, the lower its CombiRank number. When two Pals breed, the game averages their CombiRank values using the formula floor((PowerA + PowerB + 1) / 2) and then selects the Pal whose own CombiRank is closest to that result. Understanding this math is the key to unlocking any Pal through breeding chains.
However, before the formula runs, the game first checks a hardcoded list of Unique Breeding Combinations. These are special pairs — like Relaxaurus + Sparkit producing Relaxaurus Lux — that bypass the CombiRank math entirely. Our calculator checks these unique combos first, then falls back to the standard formula, exactly mirroring the in-game logic so you always see the correct result.
