YaxNer is a rare Runeword created by combining a Yax Rune of Ritual and a Ner Rune of Invocation.
How to Create YaxNer
You can create YaxNer by adding the magic Yax Rune of Ritual and the rare Ner Rune of Invocation to a two-socketed Helm, Chest Armor, Pants, or Two-Handed Weapon.
Yax - Drink a Healing Potion. (200)
Ner - Invoke the Rogue's for 5 seconds, gaining Dodge Chance, Movement Speed, Unstoppable, and Stealth. (600)
Countering Concealment
Overflow
YaxNer can not overflow because the amount of Offering you receive from the Yax 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.
