NeoTal is a rare Runeword created by combining a Neo Rune of Ritual and a Tal Rune of Invocation.
How to Create NeoTal
You can create NeoTal by adding the rare Neo Rune of Ritual and the magic Tal Rune of Invocation to a two-socketed Helm, Chest Armor, Pants, or Two-Handed Weapon.
Neo - Avoid health damage while fighting for 2 seconds. (200)
Tal - Invoke the Spiritborn's Pestilent Swarm, dealing damage to enemies. (100)
Overflow
When NeoTal overflows, you receive the Tal Rune's overflow effect (Increased Swarms Spawned) 1 times.
Overflow occurs when your Ritual generates more Offering than required for the Invocation. The overflow effect is proportional to the amount Offering overflows.
