Talos-II holds plenty of secrets, but sometimes the most obvious reward is the most exciting. Amongst the myriad chests spread around the areas of Arknights: Endfield are sealed crates, required a bit of scouting for a bigger reward.
The very first of these players will have access to is right outside the Hub Base, offering a nice little boost to early progression if you can find the three Sealing Aurylenes. Here, we’ll show you where each is and nab them!

How to open the Sealed Crate in the Hub Base Power Plant

Sealed Crates are special in that you can’t just open them when the coast is clear of enemies. Each Sealed Crate has three pieces of Sealing Aurylenes that keep it shut that you’ll need to find.
Some require a keen eye, a little platforming, or careful placement of transmission pylons to power outdated equipment. Our very first requires all three, so let’s get to it!
Sealing Aurylene 1

The easiest of the Aurylene’s to snag is directly to the chest’s right. If you look up by a nearby outpost facility, you’ll see if floating above a few boxes.
This one couldn’t be simpler: just walk around the building, climb the stairs, and hop onto the box to snag the first Aurylene!
Sealing Aurylene 2

While you’re walking around the building to climb the stairs, you’ll likely notice the second Aurylene behind a laser gate. The nearby switch lacks the power to disable it, but we can fix that!
Just up the hill is the tutorial for connecting pylons with power cables after all! Ensure your pylons are connected, then trail a cable over the Electric Nexus connected to the switch. The only thing to keep in mind here is the 80 m limit for the cable; the rest of everything should be pretty easy to set up.
From there, just flip the switch to cycle the gate’s power and secure your second Aurylene.
Sealing Aurylene 3

To the chest’s left, you’ll see another laser grid blocking off the Sealing Aurylene. This one is already powered, meaning you can flip the nearby switch to disable it and walk inside.
This is also where you can find the tutorial for broken power generators, which surround the Aurylene. With a few resources, you can set up these stations for additional power in the area.
Sealed Crate Rewards

For securing the chest, you’ll get some Oroberyl, EXP materials, and a free purple weapon! For this chest, I got an Aggeloslayer, a solid starting weapon for Spear users!
Every little boost helps, especially with the grind expected from Gacha like Endfield. Keep an eye out for Aurylene, chests, and anything else that points them out!
