The quest titled "There Can Be Only One" in The Witcher 3: Blood and Wine expansion offers players the opportunity to obtain one of the most powerful steel swords in the game, Aerondight. To prove worthy of this legendary weapon, Geralt of Rivia must embody the five chivalric virtues held dear by the knights of Toussaint: Compassion, Generosity, Honor, Valor, and Wisdom. Understanding how to demonstrate these virtues during your adventures across the duchy ensures you can claim the sword without unnecessary delays.
Demonstrating Compassion and Generosity
Compassion can easily be proven during several side quests throughout Toussaint by showing mercy to defeated foes or unique beasts. For instance, sparing the silver basilisk during the quest Mutual of Beauclair's Wild Kingdom satisfies this requirement instantly. Alternatively, choosing non-violent resolutions during key storyline encounters also signals Geralt's mercy to the Hermit on Lac Célavy.
Generosity requires a simple act of charity within the city of Beauclair. You can fulfill this virtue early on by tipping the messenger child who delivers a letter to Geralt at the main square. Donating money or opting to overpay locals during minor encounters also satisfies the Hermit's expectations.
Fulfilling the Virtues of Honor and Wisdom
Honor demands that Geralt keeps his word and abides by chivalric traditions during tournaments or personal duels. Competing in the Warble of a Smitten Knight quest line and accepting duel challenges under your true name offers a direct path to proving your honor. Defending your title fairly guarantees that this virtue is recorded in your favor.
Wisdom is best demonstrated by making insightful choices during complex investigations and riddle-solving opportunities. Successfully solving the riddles during La Cage au Fou or finding the correct solution during the main story questline counts toward proving Geralt's sharp intellect. Avoiding rash violence in favor of clever dialogue choices consistently rewards the player in this category.
Proving Valor and Facing the Hermit
Valor involves facing formidable challenges and taking on heroic tasks without hesitation. Completing the grand tourney or defeating dangerous monster contracts across Toussaint easily proves Geralt's combat bravery. Once all five chivalric virtues are validated, you must return to Lac Célavy to speak with the mysterious Hermit waiting on the island.
The final step of the quest requires Geralt to engage in a duel against the Hermit himself to prove ultimate mastery. Upon defeating him in combat, the Lady of the Lake appears to bestow Aerondight upon the witcher. This exceptional sword scales its damage with Geralt's level, making it a permanent centerpiece for high-level endgame builds.
