In Hogwarts Legacy, potion brewing is a crucial aspect of gameplay—whether you're preparing for a tough boss fight or simply want to stay alive longer during exploration. From the healing Wiggenweld Potion to the powerful Thunderbrew, each elixir requires specific ingredients. While some can be grown or crafted in your Room of Requirement, others must be farmed in the open world or purchased from vendors.

Rather than wandering aimlessly across the map, it's a good idea to learn about the best places to farm potion ingredients, and some players have the option of Buy Hogwarts Legacy Data Boosting Service to save valuable time. Below are seven top-tier locations in Hogwarts Legacy that consistently yield the resources needed for potion crafting. Remember: all ingredients respawn every three in-game days, so plan your routes accordingly.

Hogsmeade Valley & Horklump Hollow: Great for Mongrel Fur & Horklump Juice

The Hogsmeade Valley region is home to several Beast Lairs, offering reliable sources of Mongrel Fur. Head southeast of the East Hogsmeade Valley Floo Flame to find a Mongrel Lair with repeatable drops.

Meanwhile, Horklump Hollow, located in northern Hogsmeade, is the ideal spot to gather Horklump Juice. This dark, cavernous area is crucial for players brewing Wiggenweld Potions. Horklumps are easy to spot and respawn regularly, making this a must-visit location.

Feldcroft Region:  Ideal for Troll Bogeys & Dugbog Tongues

If you're hunting for Troll Bogeys or Dugbog Tongues, the Feldcroft Region offers several prime farming locations. Start from the North Feldcroft Floo Flame, then loop around the Rookwood Castle area to encounter two Troll Lairs. Another lair is located just north of the Feldcroft Catacomb.

To farm Dugbog Tongues, follow the rivers and coastal areas. The southeast part of the Feldcroft Region has a dense population of Dugbogs. Explore the region south of the Moonstone Garden Dungeon, where a Dugbog Lair and river system provide abundant ingredients.

The South Sea Bo: Perfect for Leech Juice & Stench of Death

For players crafting healing potions, Leech Juice is essential. The South Sea Bog is a haven for Leeches, especially around the wet areas and shallow waters. Begin your journey south of Lower Hogsfield, then trace the riverbanks and lakes to gather dozens of Leech clusters in a single loop.

This area also hosts Inferi, which drop the Stench of Death—a rare ingredient used in high-tier potion crafting. Inferi are most commonly found in Inferi Lairs, especially south of the Northern South Sea Bog Floo Station or east of San Bakar’s Tower in North Ford Bog.

The Forbidden Forest: Spider Fangs & Mongrel Fur

The Forbidden Forest is one of the best zones to farm Spider Fangs, which are required for potions like Thunderbrew. Look northeast of the Forbidden Forest Floo Flame for multiple Spider Lairs filled with aggressive spiders ready to drop fangs.

This forest also crawls with Mongrels, allowing players to collect more Mongrel Fur while exploring. Since both ingredients are commonly needed, this area offers a two-for-one farming opportunity.

Perimeter of Hogwart: Lacewing Flies & Ashwinder Eggs

Just outside the Hogwarts Castle, players can find Lacewing Flies—small glowing insects that are best collected at night. These flies congregate near bushes and grassy trails, especially along the roads leading away from the school and into the Forbidden Forest.

Meanwhile, Ashwinder Eggs, which appear as bright orange clusters, are commonly found along rocky cliffs and mountain paths. Try exploring the area near the Quidditch Arena, especially south of the Mooncalf Den Floo Flame, and then work your way around the perimeter of the castle.

Poidsear Coast: All-in-One Region for Lairs and Ingredients

Poidsear Coast is arguably one of the most ingredient-rich regions in the game. Begin at the Tomb of Treachery Floo Flame and head south to access multiple enemy lairs. You’ll encounter:

· A Troll Lair for Troll Bogeys

· A Spider Lair for Spider Fangs

· A Mongrel Lair for Mongrel Fur

Continue exploring the coastline for Dugbogs, especially near rivers and marshy areas. One standout location is southeast of the South Poidsear Coast Floo Flame. Also, a group of six Treasure Vaults between the Poidsear Castle and Marunweem Bridge Floo Flames holds a variety of enemy spawns and gatherables for bonus ingredient farming.

Room of Requirement: Best Passive Potion Ingredient Farm

Your Room of Requirement is the ultimate farming location, offering tools for both active and passive resource collection. Here’s what you can set up:

· Material Refiner: Generates 10 Moonstones every 10 minutes

· Potting Tables: Grow essential potion ingredients like Shrivelfig Fruit (for Thunderbrew) and Fluxweed Stem (for Focus Potion)

· Vivarium: Use Nab-Sacks to rescue magical Beasts like Mooncalves, then groom them for ingredients or sell them for gold

· Breeding Pen: Breed Beasts to collect more ingredients or build up a passive gold income

This customizable hub ensures you never run out of the most vital ingredients, especially for long-term brewing plans.
