Crossbows are excellent fallbacks for your party in Baldur’s Gate 3. When the enemy is just too far away, or maybe when you want a little distance, they’re always there for you. And the Hellfire Engine Crossbow adds some heavy artillery to your Baldur’s gate 3 arsenal.
This special crossbow can be crafted in Act 3 of Baldur’s Gate 3, once you’ve reached the Lower City. It’s tied into the quest to Disable the Steel Watch, but before you going blowing the place to smithereens, take a tour through the factory. The Hellfire Engine Crossbow is very much worth picking up, especially for the ensuing fights in the Foundry.
Where to find the Hellfire Engine Crossbow blueprint
The blueprint is the key part of the Hellfire Engine Crossbow DIY project in Baldur’s Gate 3, and you can find it inside the Security office at the back of the Steel Watch Foundry. The tricky part is that while you can read it, you will actually need to pick it up. Open the options menu on it (right-click for PC players) and opt to add it to one of your party member’s inventories.
Next, we’ll need the materials. They’re scattered around the factory’s ground floor, so you don’t need to advance further just yet to find them. You will probably want to finish the fight on the ground floor though, just to make life easier.
The parts you’re looking for are:
- Targeting Module
- Steel Watcher Arm
- Watcher Crossbow Blueprint
- Table
The first two are scattered around the factory, while the blueprint is in our possession already at this point and the table is located on the opposite side of the Security office, near the stairs.
How to make the Hellfire Engine Crossbow
Now, head to the table and interact with it. You should have the combining screen show up. Open your inventory, and drag-and-drop the Steel Watcher Arm, Targeting Module, and Blueprint onto the slots next to the Table.
Hit the Combine button, and it will eat up the components and spit out the Hellfire Engine Crossbow. Congrats!
This special Heavy Crossbow has some nice bonuses. It hits hard, comes with a +2 Weapon Enchantment, can perform several special shots including one that reels enemies closer, and gets Lightning Arrow as a spell. It’s a very handy weapon in the hands of someone like Karlach, giving her a much more effective ranged option than a normal, boring crossbow.
