Originally introduced in Shadows of Evil, the Apothicon Servant essentially creates a portal that sucks in and destroys all nearby zombies – kind of like the Gersch Device. In Black Ops 3 Zombies Revelations, you first need to acquire the weapon out of a Mystery Box – it cannot be built like in Shadows of Evil.
Once you’ve gotten your hands on the Apothicon Servant, you can start upgrading it via a PaP to make it one of the most dangerous weapons in Call of Duty Black Ops 3 Zombies Revelations.
How to get the Apothicon Servant
Acquiring and upgrading the Apothicon Servant, a.k.a Estulla Estoth, is a straightforward task, but it can take a considerable bit of time. All you have to do is open a Mystery Box to get the wonder weapon. When it comes to upgrading the gun though, you may have a bit of trouble.
How to upgrade the Apothicon Servant in BO3 Zombies Revelations
In order to begin, you must activate all x4 Corruption Engines and unlock the Pack-a-Punch. You can check out Pack-a-Punch Location Guide to learn how to do it.
Once you have unlocked the PaP, you need to shoot a total of x5 blue crystals in the sky using the Apothicon Servant. The locations of these crystals are:
- Der Eisendrache – Near the Ritual Area (Corruption Engine)
- Mob of the Dead – Near the Ritual Area
- Nacht der Untoten – On the Left Side of Apothicon Creature
- Verruckt – Near the Ritual Area, on the Right Side
- Verruckt – Near the Jump Pad on the Upper Side
Once you are done with all x5 blue crystals, head over to Pack-a-Punch Machine and notice the blue dots all around it! Now it is a simple matter of inserting the Apothicon Servant into the Pack-a-Punch and getting it upgraded!
When the Apothicon Servant is upgraded, it receives a new name – the Estoom-oth – and obtains a purple appearance rather than a red one in BO3 Zombies.
