RuneScape Dragonwilds has a brand new quest featuring Doctor Fenkenstrain. If you happened to notice a new building in Bloodblight Swamp’s southern Lodestone, the quest begins there. What should excite you are the rewards, as you get the Zombie Arm weapon, alongside the Lightning Rod. If you’re looking for the Zombie Arm, in this guide I’ll tell you how to get it. However, I have to say this quest is long, but the ending is certainly worth the effort.
Things You Need To Do Before Doing the Great Body Robbery Quest

To start The Great Body Robbery quest, you first need to travel to Doctor Fenkenstrain in Bloodblight Swamp. But before heading there, I’d recommend you carry a large number of Antipoison potions; otherwise, you’ll lose a lot of health without aid. It’s best to make Antipoison II since it lasts longer (300 seconds) and grants 66% poison resistance. To make one, you’ll need the following items:
| Item Required | Where To Find Them |
|---|---|
| Irit | Acquired from destroying Thorny Irit Roots. |
| Poison Ichor | Collected by killing Wild Jade Vines and Putrid Rats. |
| Glass Vessel | Created with Molten Glass at Jeweler’s Bench. |
Make sure to collect multiple of each required item, since you’ll need to make multiple potions. Once done, interact with a Brewing Cauldron and craft the mentioned potion. With that done, it’s time to travel to Bloodblight Swamp and use the potion whenever the poison buildup begins.
How To Complete the Great Body Robbery Quest

To start the new Great Body Robbery quest, you need to travel to the southern Lodestone in the Bloodblight Swamp. Right next to the Lodestone, you’ll find a small stone castle, and on the second floor, you’ll find Doctor Fenkenstrain. Talk to the NPC to start the quest. I’d recommend you use a mount since there is a lot of traveling involved.
The first stage requires you to collect three body parts spread across Bloodblight Swamp. Now you don’t have to travel much for this quest, since most of the items are present close to each other. I’ve marked the location of all three coffins on the map below. Simply go to the location and dig up the coffins at the grave.

After collecting all the body parts, make your way back to Doctor Fenkenstrain. Upon interacting, you’ll be asked to place the body parts on the examination table on his left. However, the quest does end here as you’re asked to make three distinct potions to use on the experimental body, and they are as follows:
- Weak Antipoison Potion (1 Marrentil, 1 Bittercap Mushroom, and 1 Clay Vessel)
- Weak Focused Attack Potion (1 Marrentil, 1 Small Animal Fang, and 1 Clay Vessel)
- Weak Lumberjack Potion (1 Harralander, 1 Antler, and 1 Clay Vessel)
After completion, the last stage of the quest requires you to collect Lightning-In-A-Bottle. This part of the quest was a bit tricky for me, but it’s rather simple. All you have to do is carry the Empty Vial received from Doctor Fenkenstrain and travel to Stormtouched Highlands to get struck by lightning. Once that happens, you’ll have the item in your inventory. However, do make sure you have an ample amount of health beforehand; you might end up dying.
For the final time, return to Doctor Fenkenstrain and interact with the Strange Machine, present on his left side, and place the Lightning-In-A-Bottle. This is the final stage of the quest, and you’ll receive the Zombie Arm melee weapon, alongside Lightning Rod. Zombie Arm is a great Power Level electrifying mace weapon, with the following stats:
- Base Damage: 56-99
- Block: 23
- Durability: 1300
- Damage Type: Crush
The Lightning Rod is also a great decorative item for your base, as it intercepts any nearby lightning strike. So, if you had plans to make your base in a place where lightning is prevalent, this item will make it possible for you.
