Lifestone shards (2x)
The Lifestone shards here are tricky. One is acquired after smashing all eight of the cross tombstones in the cemetery. For expediency, the video shows only the final one and the location of the chest. The second is stashed in the small building near the gate, and requires both the Crossblade and the Tremor Gauntlet.
Artifact: Soldier (2x)
Requires: Tremor Gauntlet
On the way to The Broken Stair, there's a spot where you have to Shadowglide across a short chasm. Look down and to the left for the blue crystals. Smash them with the Tremor Gauntlet and collect your Champion artifact.
