PocTon is a rare Runeword created by combining a Poc Rune of Ritual and a Ton Rune of Invocation.
How to Create PocTon
You can create PocTon by adding the rare Poc Rune of Ritual and the magic Ton Rune of Invocation to a two-socketed Helm, Chest Armor, Pants, or Two-Handed Weapon.
Poc - Spend 5% of your Maximum Resource. (5)
Ton - Invoke the Sorcerer's ites, dealing damage to enemies. (20)

Overflow
PocTon can not overflow because the amount of Offering you receive from the Poc Rune exactly fills the required Offering of the Ton Rune.
Overflow occurs when your Ritual generates more Offering than required for the Invocation. The overflow effect is proportional to the amount Offering overflows.
