The Tainted Soul Pill in Lineage Piece comes from a single source, so getting it fast means running the same fight over and over. There is no crafting recipe, shop purchase, or code that hands it to you. You earn it by killing one specific boss and hoping the drop lands.
Quick answer: Travel to Hueco Mundo Island, find the Ichigo (Bankai) boss, and defeat it repeatedly. The Tainted Soul Pill is a random drop, so keep clearing the boss until it appears in your inventory.
Where the Tainted Soul Pill drops
The pill is tied to the Ichigo (Bankai) boss, which spawns on Hueco Mundo Island. That boss is the only known way to obtain it. Because the item is a random reward, a single kill will not guarantee it. Some runs give you nothing useful, while others drop the pill alongside loot like an Epic Chest, Blue Solar Lily, or Epic Ore.

How to confirm you got it
When the drop succeeds, the Tainted Soul Pill lands directly in your inventory after the boss is defeated. Open your inventory and check for the item by name to verify it. If it is not there, the roll simply did not favor the pill that run.
The only reason it fails to appear is the random drop rate. There is no hidden requirement or extra step to unlock it, so the fix is always the same: clear the boss again and take another chance at the drop.
Tip: Killing the boss faster increases how many attempts you get per session, which is the most reliable way to speed up the grind. A high-damage build shortens each fight and lets you rerun Ichigo (Bankai) more often before the pill finally drops.
