Rage Juice

Awarded for completing The End with the Fighter class. Unlocks Rage Juice, a consumable trinket. When used, it grants +4 STR, +4 SPD, Brace 2, and Madness for the rest of the battle, usable once per battle. A massive offensive boost that pairs perfectly with Fighter builds focused on raw physical damage, though the Madness effect means you lose control and must weigh the tradeoff carefully.
