Diablo 4 A Sliver of Light continues Shobβhaβs questline, and it is the third quest you must complete to save the thicket from the corrupted magic that killed Barret.
A Sliver of Light also introduces Shobβhaβs second familiar, named Mochrann, who will help you progress the quest line and continue your investigation of the corrupted ancient magic that poisoned Berretβs heart.
During D4 A Sliver of Light, youβll get to find more clues by investigating some fonts of corruption. Our walkthrough below reveals where to find the fonts of corruption and how to complete the quest named A Sliver of Light in the latest video game developed byΒ Blizzard EntertainmentΒ for PlayStation 4, PlayStation 5, PC, Xbox One, and Xbox Series X/S.
How To Start A Sliver of Light Quest in Diablo 4
Diablo IV A Sliver of Light requires you to progress the associated questline by completing the previous two side quests: A Deepening Shadow and The Old Ways.
At the end of the second side-quest, youβll automatically start A Sliver of Light when the old Shobβha asks you to find Mochrann.
As you can see on the following map, Mochrann is found several steps west of Shobβhaβs location near Tur Dulra Stronghold.

When you get to the location marked on our map, youβll discover that Mochrann is a Wildwood or a giant tree if you want.
After interacting with Mochrann, youβll receive a new objective that asks you to bring him to the first font of corruption.
Where To Find the Diablo 4 Fonts of Corruption
Diablo 4 Fonts of Corruption are magic pools you must find within specific search areas during A Sliver of Light side quest.
To find the first one, open your map while tracking the current quest, and youβll see the first search area south of Tur Dulra Stronghold in the Scosglen region.
It is on the same hill you investigated while looking for Barret during A Deepening Shadow.
Make sure that once you get to the top of the hill in the center of the search area, you get close to the red magic pool pictured below.

Eventually, youβll see Mochrann absorbing the foul magic and be asked to find the second font of corruption, located west of your current location.
Make your way to the second search area and stay close to Mochrann because youβll be ambushed by several mobs. Kill them while near Mochrann and notice how he absorbs the corrupted magic.
Finally, youβll have to travel further southwest to find the final D4 Font of Corruption, partially hidden close to the mountain wall. You should be able to spot it near the center of the search area.

When you get close to the pool, while Mochrann absorbs the magic, you must deal with the mobs that ambush you so you can fill the red bar on the right side of the screen. Notice the circle on the ground and stay within its borders.
Wait for the mobs to get inside the circle and kill them to fill the bar. Unfortunately, the ritual leads to Mochrannβs death, but you have repelled the corrupted magic infesting the forest.
Now itβs time to head back to Shobβhaβs location northeast of Tur Dulra. Talk to her, and sheβll know that her second familiar is dead.
For saving the thicket and completing Diablo 4 A Sliver of Light, youβll receive Gold, XP, Renown Points, and The Croneβs Blessing rare ring.
