To unlock this achievement, you must craft a Tripwire Trap.

The recipe for Tripwire Trap can be acquired from any shopkeeper or blacksmith. However, you don’t need to have the recipe to craft it. You can simply combine the ingredients to learn the recipe and craft your first Tripwire Trap. The ingredients are x2 Iron Scrap, Wood, and Linen Cloth. Iron Scraps can be purchased from any blacksmith or shopkeeper, or looted from Armored Hyena, Animated Skeleton, Ash Giant, Forge Golem, or Troglodyte Knight. Linen Cloth can be purchased from most vendors, or crafted by combining 2 Bandages.
