Raphael’s Old Enemy (Yurgir) (Umbral Gem 1)
Go up the steps on the east side of the Gauntlet of Shar Waypoint. Then proceed to the far left corner and leap down the ruined stairway.
Follow a Beast until you reach a chamber full of corpses. Refer to the exact location.
The Yurgir and its minions will ambush you here. Keep talking about the pact that binds him here until you unlock a persuasion check that will convince him to slaughter his group and then himself.

Finally, pick up the Umbral Gem #1 on the staircase next to its throne.
Soft-Step Trial (Umbral Gem 2)
From the Gauntlet of Shar Waypoint, go down the stairs on the north and enter the first room on the left. Offer your blood as a sacrifice in front of the statue to begin Soft-Step Trail. Refer to the exact location.
In this trial, you must slip through a little maze to the end. There are shadows patrolling the environment, and you must avoid being detected by these shadows and also avoid the traps.
Use a sneaky character and an invisibility potion. To complete the trail, enter through the leftmost tunnel, hug the wall, leap through a window, then turn right until you see a large gate.
To complete the trial, pick the gate’s lock and take the Umbral gem #2.
Self-Same Trial (Umbral Gem 3)
From the Gauntlet of Shar Waypoint, go down the stairs on the north and enter the second room on the left. Refer to the exact location.
This trial forces you to fight a clone of your parties. If you have Karlach in your party, for example, a clone of Karlach will emerge, and she must only fight that clone and not anybody else’s. The Last you defeat will drop Umbral Gem #3
Faith-Leap Trial (Umbral Gem 4)
From the Gauntlet of Shar Waypoint, go down the stairs on the north, continue to walk along the hallway, and then descend on the right and through the first door. Refer to the exact location.
This trail will require players to traverse a gap using invisible platforms. Enter the chasm from the left and walk over it until you reach the left statue.
Hug the left wall and descend to an invisible platform. Turn right and continue on the path toward the middle platform and then jump or fly to the statue. You can simply leap across the stone platforms bearing Lady Shar’s statue. Make sure to first step onto the invisible pathways before jumping or flying.
Drop down from the rightmost side of the middle platform with the statue. Slowly approach the Umbral Gem, then leap to the platform containing the Umbral Gem #4.
