The Hellfire Engine Crossbow

In Baldur’s Gate 3, the Hellfire Engine Crossbow is a two-handed range weapon you can get in Act 3. You can equip it to your character’s main hand weapon slot in the inventory, providing additional bonuses and buffs. The user needs Martial Weapon proficiency or suffers penalties while wearing the weapon.

Among its bonuses, the weapon has decent damage and will be a perfect high-damage range weapon for Fighters, Paladins, or Barbarians. Proficiency with this crossbow unlocks the Reposition Malefactor action that can pull enemies to the user if they fail the dexterity saving throw. It allows primarily melee characters to close the distance while dealing damage.

Also, with Hellfire Engine Crossbow, you can cast the Lighting Arrow spell once per long rest. It deals with a single-target attack that inflicts additional damage to nearby enemies.

How to Get the Hellfire Engine Crossbow in Baldur’s Gate 3?

You must find the Watcher Crossbow Blueprint, Targeting Module, and Steel Watcher Arm in Steel Watch Foundry to craft Hellfire Engine Crossbow in Baldur’s Gate 3.

To get the Hellfire Engine Crossbow, head to the Steel Watch Foundry (X: -291 Y: -163). It is located on the west in Lower Baldur’s Gate City in Act 3, and it is also where you can get the most powerful legendary Bow Gontr Mael. We suggest also checking out the guide on how to get it because as soon as you enter the Steel Watch Foundry, quests related to obtaining the weapon will trigger.

The area around the Steel Watch Foundry (X: -291 Y: -163) is guarded by Steel watchers and other Gortash guards. Make your way inside by unlocking the door with a 20 DC Slight of Hand skill check. You will be automatically presented with the cutscene. You can sneak inside and try to collect the required items unnoticed or pick up the fight with the guards and try to save oppressed workers, which is part of the Save the Gondians quest.

Regardless of your choices, next, you need to collect three items in this area to craft the Hellfire Engine Crossbow:

  • Watcher Crossbow Blueprint (X: -331 Y: -155)
  • Targeting Module (X: -305 Y: -156)
  • Steel Watcher Arm (X: -280 Y: -164)

The Watcher Crossbow Blueprint (X: -331 Y: -155) is on the table in the office, the closed room.

You can read the blueprint, but you will also need it to craft the Hellfire Engine Crossbow, so add it to your inventory.
