Co-op shooter Remnant: From the Ashes offers multiple avenues of customizing your character. Alongside guns, you can also equip different mods, like the Iron Sentinel, to enhance your abilities.
While there are several ways to obtain mods, the Iron Sentinel is one of those you'll need to craft. This, naturally, means you'll have to farm materials during your monster blasting sessions in Remnant: From the Ashes.
Remnant From The Ashes Iron Sentinel Mod
The Iron Sentinel mod summons an automatic turret that shoots your foes for 20 seconds. In order to craft it, you'll first need to find 1 ancient core and 5 lumenite crystals.
Where the lumenite crystals can not only drop from Remnant: From the Ashes' enemies but also be purchased from Ace in Ward 13, the ancient core requires a bit more work.
Specifically, you're going to have to take down the Ancient Construct boss on Rhom. Not only will you need to get a lucky world roll to have the boss, you're also going to put some effort in to trigger the boss fight.
What this means is that you'll have to get the Control Rod to drop from Maul or by breaking the Houndmaster NPC's head. After that, you'll have to place it into the chest of the Vyr automaton that's just outside of Wud's shop.
Remnant: From the Ashes is out now on PC, Xbox One and PS4.
