This quest requires you to craft a mechanical bow, a mechanical shockwave and a mechanical explosive bow. Let's go trough what it takes to craft each one.

The mechanical bow requires a makeshift bow and 4 mechanical parts. The makeshift bow can be found around the map and from opening chests.

The mechanical shockwave bow requires a mechanical bow and 2 shockwave grenades. The mechanical bow can be found around the map but it is probably easier to craft one yourself. The shockwave grenades can be obtained as floor loot, from chests, llamas and supply drops.

The mechanical shockwave bow is good for knocking opponents into the storm during the later stages of the game when the circle is small and the storm damage is high. You can use it to move faster across the map but the effect isn't as powerful as shockwave grenades because you get much more shots of the shockwave bow providing you have the arrows.

The mechanical explosive bow requires a mechanical bow and 6 grenades. The mechanical bow can be found around the map but it is probably easier to craft one yourself. The grenades can be obtained as floor loot, from chests and supply drops.

When you fire an arrow from the explosive bow it will spawn three small explosives when it hits it's target. This is good for shooting into an opponents fort and if there are several opponents bunched together.
