The Siege of Bastion's Keep Diablo III Guide

Last update: 11 May 2016

You begin in the Bastion's Keep Watchtower. Speak with Tyrael who should be standing next to you to get your first assignment. Descend the stairs afterwards and enter the Armory.

Signal beacons in the Skycrown Battlement's lit (5)

You'll meet Leah and Adria here and you should also notice the Black Soulstone. Proceed to the next door.

Enter the Bastion's Keep Stronghold. This location is the central part of the city and this means you'll find merchants here, as well as a blacksmith, a jeweler and companions for hire. Proceed to the gate located next to the blacksmith.

Be careful, because you're going to be attacked by Demon Troopers here. They're big, however they're not a serious threat, mostly because they don't have a lot of health points. Witness the vision of Azmodan which will be a taste of things to come.

Once you're ready proceed to the door leading to the Skycrown Battlements.

Begin exploring the Skycrown Battlements. This is a large location that forces you to travel through the stronghold's defense walls. Your primary objective at the moment is to light five signal beacons. Naturally you will be constantly interrupted by monsters and most of them will be more dangerous than the creatures encountered in the previous acts.

You've already fought with the Demon Troopers in the previous location. Aside from them you'll also be dealing with Fallen Hellhounds (they don't die as quickly as they should and they usually appear in groups), Fallen Grunts (they're not a serious threat), Fallen Prophets (they can resurrect Fallen Soldiers), Fallen Mongrels (they have a lot of health points), Fallen Overlords (they're also hard to kill and they have a powerful bashing attack) and Demonic Hellflyers (not only they can fly, but they also spit fireballs). I recommend that you always focus on the creatures with the abilities of resurrecting their kind.

Watch out for enormous Demonic Hellbearers. They are clinging to the stronghold's walls and spit new monsters from their mouths, usually new Demon Troopers. It's not easy to kill a hellbearer, because you'll have to deal with all the monsters it spat out first.

Another danger you must be aware of are huge objects landing on the stronghold's walls. Red circles marks areas where they will land, however you can't anticipate where smaller projectiles will hit the ground.

Follow the only route through the stronghold's walls, locating and activating signal beacons along the way. Each beacon will be defended by a single Demonic Hellbearer. Continue your journey until you've lit all five beacons. It's worth adding that you may also encounter Colossal Golgors while trying to complete this objective. They're slow, however they have a lot of life points and their attacks are very strong.

Find Sergeant Dalen in the Skycrown Battlements

Keep exploring this location even after you've lit all five beacons and you will soon encounter Sergeant Dalen. Watch another vision of Azmodan which will end this quest.
