Where to Find the Infernal Rapier

Location: House of Hope

The Infernal Rapier is located in the House of Hope, a late-game area in Act 3 of Baldur’s Gate 3. This region can only be accessed through a specific portal found within the city. To begin your journey toward acquiring the Infernal Rapier, you’ll first need to unlock access to the House of Hope.

Step 1: Reach Act 3 and Find Helsik

Once you’re in Baldur’s Gate during Act 3, head to the Devil’s Fee. Inside, you’ll meet Helsik, a devil-worshipping NPC who can help you access the House of Hope. You must complete a puzzle for her, which involves placing specific items on a summoning circle in a particular pattern. These items typically include a skull, an infernal marble, a coin of Mammon, a diamond, and incense.

Step 2: Open the Portal to the House of Hope

When you place the items correctly, Helsik will cast a spell that opens a portal to the House of Hope. Before entering, ensure your party is fully prepared. This area includes one of the toughest optional bosses in the game Raphael and exploring it can lead to several critical decisions and rewards.

Step 3: Explore the House and Find the Rapier

Within the House of Hope, explore the halls carefully. The Infernal Rapier is not given freely it is kept in a vault protected by puzzles and possibly combat encounters. Look for clues about Raphael’s secret vault. The Infernal Rapier is often found alongside other powerful artifacts like the Helldusk Armor, and it may be stored in the same treasure room or magical container.

How to Access Raphael’s Vault

Finding the Vault

Inside the House of Hope, you’ll need to locate Raphael’s private quarters. In this room, look for hidden levers, magical runes, or disguised doors that lead to the vault. You might need to pass perception checks or disarm traps along the way. This area rewards keen exploration and careful interaction with the environment.

Optional: Stealth and Dialogue

If you wish to avoid combat, you can use stealth tactics and dialogue choices. In some playthroughs, it’s possible to distract or deceive Raphael’s guards, allowing you to move freely. Characters with high Charisma or Dexterity can have an easier time navigating these challenges non-violently.
