Sentinel
(Redirected from Apex sentinel)
This page is about the item class and its corresponding game mechanics. For the notable passive skill, see Sentinel (passive skill). For the monster mod "Sentinel", see Archnemesis modifier. For the expansion, see Sentinel (expansion).
Note: Sentinel is not yet added to the core game as Extra Content. It can be found in certain special events only
Sentinels are a type of item that are exclusive to the Sentinel league. They can be deployed to empower enemies, making them stronger but more rewarding.
Types of Sentinels
There are three types of Sentinels.
Stalker Sentinel
Stalker Sentinel fires beams periodically to empower enemies.
Pandemonium Sentinel
Pandemonium Sentinel fires a beam once, chaining to multiple enemies. Unlike the other types, it will disappear after firing its beam once, even if it didn't get to empower the maximum number of enemies.
Apex Sentinel
Apex Sentinel fires a beam to empower enemies, but it only targets Rare and Unique monsters.
Mechanics
Sentinels can be found in Sentinel Caches that can randomly appear in zones. They can also drop from enemies. The first Sentinel Cache you open with your character will drop a Sentinel Controller, giving you access to the Sentinel Controller and adding Sentinel equipment slots.
When a Sentinel is deployed, it will follow you and fire beams at enemies to empower them, restoring it to full life and giving it an Empowerment buff. Empowerment increases the damage dealt and reduces damage taken by the monster, but it also increase their experience given and item yield. There is also a chance an empowered enemy gains an additional reward. The Sentinel will disappear once it has empowered a set number of enemies, is dismissed manually, or when the user dies.
You can equip one of each type of Sentinel.
Sentinels drop unidentified, but cannot have their mods modified. Sentinels also have a limited number of times they can be deployed. There is no way to add charges to a Sentinel.
Sentinels can be deployed in story zones, regular maps, Vaal side areas, the Eternal Labyrinth, Breachstones, the Temple of Atzoatl, Delve, and Invitations.
Sentinels cannot be deployed in unique maps.
Sentinel Controller
The Sentinel Controller interface, unlocked after using the 
Sentinel ControllerSentinel ControllerFor aeons, ancient constructs have lain dormant,
but now their designs are under your control.
, allows you to allocate passive bonuses to Sentinels by making connections between Runic Nodes by placing Filaments. Most Runic Nodes require only one Filament; larger Runic Nodes require two Filaments, and Sentinel Slots require three Filaments. The number of Filaments required also represents the number of power units used. Killing enemies empowered by Sentinels grant experience towards unlocking additional power units, starting at 4 up to a maximum of 30 power units at max experience. Filaments can be placed and removed freely without any cost. The Sentinel Controller configuration can be changed anywhere, but the changes will not apply until you enter a new instance and will not affect your Sentinels in the current instance.
Power Core
A Power Core allows you to combine two Sentinels (regardless of charges left) to create a new, fully charged Sentinel. The Sentinel will receive a combination of mods from both components, with a chance for unpredictable changes. Certain Sentinel base types can only be created with Power Cores. There are four different types of Power Cores:
