Bloodlines in Blox Monsters are races that you can equip to get access to their passives. Different Bloodlines offer different passive buffs like Movement Speed, increased Catch Chance, increased Rank Luck, and more. The best Bloodlines in Blox Monsters are Exile Celestial (massive Rank Luck and Mutation chance boost), Picomori (massive Catch Chance and Rank Luck boost), and Sealed Calamity (massive decrease in Hatch Time and a chance to apply a mutation).
If you want to increase your Hatch Luck, Rank Luck, Hatch Time, or hunt monsters with mutations, you need to equip Bloodlines in Blox Monsters. Bloodlines will provide different passive boosts and make your monster hunting and collecting faster and easier. In this guide, we’ll tell you how to get Blox Monsters Bloodlines, the passive buffs of each one, and which ones you should reroll for.
How to Get Bloodlines in Blox Monsters

To obtain a Bloodline in Blox Monsters, you need to talk to the Bloodlines NPC in the Misty Forest area. You can find the NPC near the spawn point, to the right of the Egg Hatcher. When you first join the game, you’ll get three Bloodline Rerolls and one Bloodline Slot for free.
Once you reach Level 7, you’ll unlock a second Bloodline Slot as well. I suggest saving up your Bloodlines Rerolls until you unlock both free slots. After that, see our best Blox Monsters Bloodlines section below to decide which Bloodlines to roll for.
You can also buy two more Bloodline Slots using Robux.
