Alright, let's talk about finding the Infernal Rapier in the House of Hope in Baldur’s Gate 3.

Here’s the good news right up front: you don’t have to beat Raphael’s big boss fight to grab this thing. The bad news? The rapier is sitting in Raphael’s personal bedroom area, right next to Haarlep the incubus. So you still have to sneak into the devil's private space and deal with that mess.

I’ve run this route a few times, so here’s the fastest path I use, how to handle Haarlep without making things worse, and the dumb mistakes that can turn an easy treasure grab into a disaster.

Why You Should Find the Infernal Rapier in the House of Hope

The Infernal Rapier is one of the best weapons in the game for Charisma-based melee builds. It’s a Rapier, so normally it counts as a Finesse weapon and uses your Dexterity for attack rolls. But the Infernal Rapier does something better: it uses your Charisma modifier for melee attack and damage rolls instead of Strength or Dexterity.

At first, that might not sound crazy. But think about it. Most melee characters have to dump points into Strength or Dexterity to hit things. The Infernal Rapier basically says, “Hey, you can ignore Dexterity and still smack people hard.” That’s huge for:

  • Pact of the Blade Warlocks
  • Sword Bards
  • Charisma-heavy Paladins
  • Multiclass builds that use Charisma as their main stat

If you’re a Warlock and you’re tired of wasting an action binding a Pact Weapon every morning, this rapier basically works like a permanent pact weapon. It’s a simple, reliable upgrade for any smooth-talker build.

Before You Walk Into the House of Hope

The House of Hope is in Avernus, but you don’t have to drag your party through the Hells to get there. You can reach it from the Lower City in Act 3. Still, don't show up unprepared.

Recommended level: 11 or higher. Some House of Hope fights can get nasty, especially if you trigger Haarlep or Raphael before you're ready.

Gold: Bring around 5,000 gold if you want the clean route through Helsik. You can try stealing from her or doing the ritual yourself, but paying is faster and way less risky.

Party setup: Bring a character with high Perception and high Sleight of Hand. You'll want to sneak through the main hall and unlock a few doors if you want all the loot. Also, bring someone who can actually use a Rapier, or this weapon won't do you much good.

Save before you enter: This isn't just a "be careful" tip. The House of Hope can lock you into some huge decisions. Make a manual save before you talk to Haarlep so you can test different dialogue options.

New player warning: Do not walk into the House of Hope with a party that's out of spell slots and healing potions. You'll regret it fast.

How To Find the Infernal Rapier in the House of Hope, Step by Step

Here's the route I use. It lets you grab the weapon early without accidentally kicking off the final House of Hope fight.

Step 1: Talk to Helsik at the Devil's Fee

Head to the Lower City and find the Devil's Fee shop. Helsik runs the place and has connections to the Hells. Tell her you're looking for the House of Hope, and she'll offer to open a portal for you.

The easiest option is to pay her around 5,000 gold. Once you pay, she gets the portal ready. Go upstairs and walk through the glowing arch to enter Avernus. That takes you straight to the House of Hope entrance.

If you're short on gold, you can steal the ritual items from her shop or basement. But doing that can turn Helsik hostile. For most players, just paying is the cleanest move.

Step 2: Make Your Way to Raphael's Boudoir

When you enter the House of Hope, you'll be at the top of a big hall. You don't need to fight every imp in the place. Move carefully, sneak if you have to, and head toward the map area that says Raphael's Boudoir.

This is the bedroom area of the House of Hope. It's usually on the same side of the main hall as Haarlep. If you see an incubus lounging around in a fancy bedroom, you're in the right spot.

Don't grab the Orphic Hammer first. That's the item that triggers Raphael's final showdown. If you grab the hammer before looting the boudoir, you can lock yourself out of a calm exploration route.

New player warning: Do not touch the Orphic Hammer until you've looted everything you want from the boudoir. That thing is the final-fight trigger.

Step 3: Deal With Haarlep the Incubus

This is the tricky part. Haarlep is Raphael's incubus, and he's just hanging out in the boudoir when you arrive. He won't attack you on sight, but he will start a conversation.

Basically, you have two real choices here:

  • Fight Haarlep. This works if your party is strong and ready for a smaller boss fight. Kill him, and you can loot the room without interruption.
  • Agree to his deal. Haarlep will let you do what you need in the House of Hope if you let him use your form. This is the non-combat option.

If you agree, you'll get a scripted scene with Haarlep. It's not game-breaking, but keep this in mind: if Haarlep lives, he can show up later during Raphael's boss fight and make things much harder.

If you want a clean boss fight later, killing Haarlep now is the better move. Just make sure your party is healthy and ready before starting that fight.

Step 4: Loot the Infernal Rapier From the Boudoir

After Haarlep is dead or distracted, search the bedroom carefully. The Infernal Rapier is in the boudoir area. Check the furniture near the bed and the small display tables in the room. The rapier sits there like normal loot, so you'll see the weapon name when your cursor passes over it.

I almost walked right past it because I was expecting a locked chest. It's not always inside a chest. Check the weapon racks, tables, and shelves in the boudoir. Once you pick it up, it's yours.

If you want to be extra careful, enter Turn-Based Mode before looting. That gives you time to look around the room without Haarlep or any remaining enemies reacting.

New player warning: Save before you talk to Haarlep, then save again before you start looting if you're nervous. Manual saves are your best friend here.

Common Mistakes Players Make When Looking for the Infernal Rapier

I've seen a ton of players mess this up. Here's what you need to avoid:

Mistake 1: Grabbing the Orphic Hammer before looting the boudoir.
This is the biggest one. The Orphic Hammer is why most people go to the House of Hope. But when you grab it, Raphael notices and the final boss fight starts. If you haven't grabbed the Infernal Rapier yet, you'll have to fight Raphael while also trying to get back to the boudoir. Don't do that. Go to Haarlep's room first.

Mistake 2: Fighting Haarlep when your party isn't ready.
Haarlep isn't a pushover. If you walk into the boudoir with low health, no spell slots, and no healing potions, that fight can go bad fast. Take a short rest or chug some healing items before you start anything.

Mistake 3: Leaving Haarlep alive and then fighting Raphael.
If Haarlep survives, he can appear during Raphael's boss fight and turn it into pure chaos. Some players skip the Haarlep fight and regret it later when they're dealing with Raphael and Haarlep at the same time. If you're not comfortable with that, kill Haarlep first.

Mistake 4: Thinking only Warlocks can use the Infernal Rapier.
Anyone with Rapier proficiency can use it. Paladins, Sword Bards, and multiclass Fighters can all make it work. The only real requirement is that you want to hit things using Charisma instead of Strength or Dexterity. Don't leave this weapon on the floor just because you're not a Warlock.

A Few Quick Build Tips After You Get the Infernal Rapier

Once you have the weapon, equip it right away if your character has proficiency. For Warlocks, this feels amazing because you no longer need to rely only on Pact of the Blade for Charisma-based attacks.

For Sword Bards, the Infernal Rapier lets you focus on Charisma and Dexterity while still landing clean hits with Blade Flourishes. Paladins get nice synergy too, since Charisma boosts both your spell save DC and your melee damage.

The Infernal Rapier also works great with a shield. Rapiers are one-handed weapons, so you can rock a shield in your off-hand and still get all the Charisma-based melee benefits.

Frequently Asked Questions

Do I have to fight Raphael to find the Infernal Rapier in the House of Hope?

No. The rapier is in Haarlep's boudoir area before you start the final Raphael encounter. You only fight Raphael if you decide to grab the Orphic Hammer after looting the weapon.

Is the Infernal Rapier better than other endgame rapiers?

It depends on your build. If you're Charisma-focused, yeah, it's fantastic. Very few rapiers in the game let you use Charisma for melee attacks, so this one is a great pick for Warlocks, Bards, and Paladins.

Can I get the Infernal Rapier if I'm not a Warlock?

Yes. You just need Rapier proficiency. Martial classes and Bards get that naturally. Even if you're not a spellcaster, you can still use the Charisma-based attacks if you multiclass into something like Paladin or Sorcerer.

Will killing Haarlep make the House of Hope harder?

Not really. Killing Haarlep before Raphael's fight means one less enemy in the final encounter. Just know that Haarlep himself can be a tough fight if you rush it. Take your time and use the environment to your advantage.

Follow this route, and you'll grab the Infernal Rapier early, dodge the worst surprises, and walk into the Raphael fight with a weapon that actually fits your Charisma build. Just remember: loot the bedroom before you go anywhere near the Orphic Hammer. Your future self will thank you.
