A lightweight Elder Scrolls Online addon that tracks the bone stack counter for the Khalnar's Nightmare monster set, helping you maximize your proc uptime and damage output.
Khalnar's Nightmare is a monster set in Elder Scrolls Online that activates after performing 5 light attacks on an enemy. Each light attack adds a "bone stack" to your target, and when you reach 5 stacks, the set procs with powerful bonus effects.
Without a visual tracker, it's difficult to know:
- How many stacks you've built on your current target
- When the set is about to proc
- If your stacks reset when switching targets
Khalnar's Nightmare Tracker solves these problems by displaying a clear, color-coded visual indicator showing your current stack count.
