The following Sentinel base types are obtainable in zones or Sentinel Caches:

• Rusted (Act 1 Stalker only)
• Bronze
• Cobalt
• Brimstone
• Emberstone
• Obsidian

The following Sentinel base types are only found in Unique form or created by Assembling:

• Cryptic (Assembly)
• Primeval (Assembly)
• Ancient
• Cosmic (Unique Apex only)

Preparing Sentinel bases

• Prepare your item filter. Normal rarity Sentinels can be safely hidden.
• Collect Sentinels from enemies or Sentinel Caches and ID them.
• Separate all Stalker and Pandemonium Sentinels with chance for Empowered Enemies to have X Reward

Regex:

  for Reward

• Optionally, remove specific rewards that are not desirable to the player

Example Regex:

   Weapon|Abyss|Gem

• Optionally, remove items with just increased chance to add Rewards (these only provide add random additional rewards)

Regex:

   "Increased chance to add"

Remaining items and normal Sentinels can be used and discarded. Keep Magic or low-value Rare Obsidians for grafting.

Grafting Sentinels

For Bronze and Cobalt Sentinels with the chance for Empowered Enemies to have X Reward modifier, you want to transfer these to a low-value Obsidian base. This process is referred to colloquially as "grafting".

• Use a Power CorePower CoreStack Size: 20Destroys two Sentinels to create a fully-charged Sentinel with a combination of their properties. Sometimes, the resultant item is modified unpredictablyRight click this item then select two Sentinels to combine. to open the Sentinel Assembly
• Insert the donor Bronze/Cobalt Sentinel and the recipient Obsidian Sentinel base (magic or low-value rare)
• Assemble a new Sentinel and check the results.
  • If you get an Obsidian Sentinel with the Reward mod, stop here.
  • If you get an Bronze/Cobalt Sentinel with the Reward mod, repeat the grafting process with a new Obsidian base.
  • If you get either base type without the Reward mod, you have lost the mod and need to start over with new Sentinels. Obsidian bases can be reused for future grafting, however.
