Hogwarts Legacyadds more combat challenges as you pick up more spells, and at some point, it kind of hits critical mass. One such challenge is “flip a Troll’s club,” which is incredibly vague. Here’s how to do it and how to complete the similarly cryptic “hit a Troll with its own boulder” challenge.
How do you flip a Troll’s club in Hogwarts Legacy?
To flip a Troll’s club, you must use the quite literalFlipendo spell. You’ll acquire Flipendo through Professor Garlick’s second assignment after you complete the initial tutorial for the herbology class in the main story. There are, however, timing considerations.
To actually get the club to flip into the Troll’s face, you’ll need to wait until itslams its club on the ground. Dodge (instead of usingProtego), and cast Flipendo when the club is on the ground. It’ll “flip” back up and smack the Troll in its face. Challenge completed!

After you’ve acquainted yourself with the timing, it’s a helpful way to take down Trolls quickly for resources.
How to hit a Troll with its own boulder
The other Troll-centric challenge doesn’t need a spell at all. Instead, you’ll be throwing a boulder (an object the Troll creates itself) withthe Ancient Magic Throwwhen the timing is right. Run far away from the Troll to coax out its boulder attack. Then, when it raises the boulder (which the game will telegraph as a Protego block), you’ll need to throw it back at them like you would any barrel or crate.
To ensure you have time to actually pick the boulder up before it hits the ground and becomes non-interactable, just tap the Triangle (Y on Xbox, Q for PC, and X for Nintendo Switch) button to cast a short Protego block.

Where to find Trolls in Hogwarts Legacy
InHogwarts Legacy, you may find Trolls atTroll Lairs and the Battle Arena. Battle Arena frequently showcases Troll battles, which can be found in the North Hogwarts Region, North Ford Bog, and Feldcroft Region. I found this creature just after starting the first round in the Feldcroft Region Battle Arena:
Troll Lair locations
If you don’t want to go through the hassle of fighting enemy waves, travel to Troll Lairs. They’ll be marked with a cave-like symbol in the following areas:
Not all symbols will feature a Troll since Mongrel and Inferi share the same icons. So, verify it is labeled as “Troll Lair.” You can use what you’ve learned with the Troll’s club and boulder to eliminate them instantly.

Where to find Troll Bogeys
Troll Bogeys are a mucus substance used in the Invisibility Potion recipe. You can get them bykilling Trolls or buying themfrom J Pippin’s Potions. You’ll likely acquire a ton of them during the challenges mentioned above. However, the shop in Hogsmeade can provide them instantly for100 gold each.
The Invisibility Potion requires Troll Bogeys, Leaping Toadstool Caps, and Knotgrass Sprig. While the Leaping Toadstool Caps can be found in forested areas, the Knotgrass Sprig seeds can be purchased at The Magic Neep for 350 gold. With all the ingredients collected, go to theRoom of Requirementand start brewing the Invisibility Potion at the Potions Station.
