NeoNer is a rare Runeword created by combining a Neo Rune of Ritual and a Ner Rune of Invocation.
How to Create NeoNer
You can create NeoNer by adding the rare Neo Rune of Ritual and the rare Ner Rune of Invocation to a two-socketed Helm, Chest Armor, Pants, or Two-Handed Weapon.
Neo - Deal damage after not taking any within 2 seconds.
(Resets if Invulnerable.) (200)
Ner - Invoke the Rogue's for 5 seconds, gaining Dodge Chance, Movement Speed, Unstoppable, and Stealth. (600)
Countering Concealment
Overflow
NeoNer can not overflow because the amount of Offering you receive from the Neo 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.
