This guide will help you get the Black Hole hidden achievement and the Abyss set introduced in the Fatesworn DLC.
How to Obtain Hidden Achievement
- (Fatesworn) Stacked at least 100 Unholy Void effects with the Abyss armor set before defeating an enemy with magic.
The Abyss Set
In order to get the Black hole achievement, you first need to find the Abyss set, you can only acquire this armour during the night.
If you explore every area thoroughly, you will have collected all four pieces by the time you reach Crownhold. With that said i have attached the local map locations.
The first piece can be found in the southern part of Revival.
The second piece can be found in the south of the open area in Three Winds Crutch.
The third part can be found in the very south of Madding Wind.
The fourth and final piece is in the Crownhold cemetery, inside the tree hollow.
The Black Hole
The achievement requires you to stack 100 Unholy Void effects and then kill an enemy with magic.
So, after making sure you meet the requirements for using the set, you should find a group of enemies and start to cast magic. Remember to heal as you will take damage while the effect is active.
I found that even blinks stack the effect but it’s probably easiest to use Mark of Flame so that you can hit multiple enemies at the same time. It shouln’t take too long for you to stack up to 100.
