Where to Get Bezoar, Ender Powder, Polar Bear Gall Bladder and Red Feather

Four reagents in the Potions Master Mod are not made at the Mortar: Bezoar, Ender Powder, Polar Bear Gall Bladder, and Red Feather. Knowing where each one comes from keeps your Cauldron supplied.

Creature-Sourced Reagents

Polar Bear Gall Bladder and Red Feather are drops, not crafts. Polar Bear Gall Bladder comes from polar bears, so travel to snowy biomes and hunt there. Red Feather is a feather-type drop; collect it from the creatures that yield it while you are out exploring. Neither can be produced at the Mortar, so treat every one you find as a limited resource and store it separately from your bulk powders.

Bezoar and Ender Powder

Bezoar and Ender Powder round out the reagent list. Ender Powder is a powder, so it fits the grinding workflow — bring the source material to your Mortar and Pestle and process it down. Bezoar is its own distinct item; gather it through the mod's available means rather than assuming it grinds out of charcoal. Keep both in your reagent chest next to Activated Charcoal and Charcoal Powder.

Stocking Strategy

Run two supply lines: a grinding line at the Mortar for Charcoal Powder, Activated Charcoal, and Ender Powder, and an exploration line for Bezoar, Polar Bear Gall Bladder, and Red Feather. Restock the exploration line on dedicated trips so a missing drop never blocks a Cauldron session.
