How to Unlock Hard Mode Brutus
After defeating Brutus in the quest, you can unlock a harder version of the fight with improved mechanics.
To unlock Demonic Brutus, you must feed hit an abyssal potato from the Scar, which requires completion of Desert Treasure II. You can get there by teleporting to Guardians of the Rift and traveling with the Catalytic Guardian or just by using the Ring of Shadows. Pick the growth to receive an abyssal potato – you’ll probably need more than one!
