YulNer is a legendary Runeword created by combining a Yul Rune of Ritual and a Ner Rune of Invocation.
How to Create YulNer
You can create YulNer by adding the legendary Yul Rune of Ritual and the rare Ner Rune of Invocation to a two-socketed Helm, Chest Armor, Pants, or Two-Handed Weapon.
Yul - Cast a Skill with a Cooldown. (50)
Ner - Invoke the Rogue's for 5 seconds, gaining Dodge Chance, Movement Speed, Unstoppable, and Stealth. (600)
Countering Concealment
Overflow
YulNer can not overflow because the amount of Offering you receive from the Yul Rune exactly fills the required Offering of the Ner Rune.
Overflow occurs when your Ritual generates more Offering than required for the Invocation. The overflow effect is proportional to the amount Offering overflows.
