Bloodlines in Blox Monsters are permanent passive bonuses that change how fast you catch monsters, how quickly eggs hatch, your movement speed, and your luck for higher ranks and mutations. Each one pushes you toward a specific playstyle, so the right pick depends on whether you are hunting hidden monsters or farming eggs and rare pets.
Quick answer: Pick ExileCelestial for the strongest all-around bonus (+200% Rank Luck and ×2 Mutation Chance), Picomori for catching hidden monsters, and Sealed Calamity or Serpent Deity for egg hatching.
All Blox Monsters bloodlines and their perks
Bloodlines split into a few clear roles. Some boost your catch chance and guarantee a minimum rank on hidden monsters, some raise rank luck or mutation chance, and a couple cut hatch time while adding bonus traits or mutations to newly hatched pets. The full set and what each one grants is below.

Best Blox Monsters bloodlines by goal
There is no single best bloodline for every player. Catch-focused bloodlines win when you are chasing hidden monsters, while hatch and mutation bloodlines pull ahead when you farm eggs and rare pets. These four cover the most useful builds.
- ExileCelestial is the strongest all-around option. The +200% Rank Luck is the largest luck bonus available, and the ×2 Mutation Chance makes it ideal for farming rare, high-value monsters.
- Picomori is the top pick for catching hidden monsters, with ×2 Catch Chance, +100% Rank Luck, and a guaranteed Rank B or higher on hidden catches.
- Sealed Calamity is best for egg hatching. It cuts hatch time by 25% and adds a 20% chance for newly hatched pets to roll a mutation.
- Serpent Deity is another strong hatch choice, reducing hatch time by 15% and adding a 10% chance for a hatched pet to receive a Legendary Trait.
How to reroll your bloodline
You only hold one bloodline at a time, so landing a strong one means rerolling through the Bloodline NPC until the result matches your goal. The reroll menu shows your current bloodline and the option to roll again.
Note: Because a reroll overwrites whatever you currently have, stop rolling the moment you get a top-tier result. Rolling again can replace a strong bloodline with a weaker one.
Match the bloodline to what you are doing right now, and you will see the benefit immediately, whether that is faster catches on hidden monsters, quicker egg hatches, or a better shot at high ranks and mutations.
