Intelligence Extract

The Intelligence Extract is a glowing blue orb that lands in your inventory the moment you finish the tutorial - whether or not you actually defeated the tutorial boss Gelum. Its in-game description plays coy ('It might be useful in the future'), and most players carry it for hours before learning what it is: the first of three extracts behind one of the game's best-hidden quality-of-life unlocks.

That unlock is the Mystery Statue Quest, started by speaking to the NPC Clint at level 15. Collect all three extracts - Intelligence (this one), Strength (from the Crocodile King) and Courage (from the Masked Warrior) - and slot each into its corresponding statue in the Soul Society Outskirts. Doing so opens a hidden portal to the skill refund shrine, where you can refund individual skills without resetting your entire skill tree or spending Robux.

As the freebie of the trio, there is nothing to farm here - the extract cannot be dropped, banked or sold, so it sits safely in your inventory until the statues are ready. The real work is the other two orbs; this one just means every player is already a third of the way to the refund shrine without knowing it.
