BacTon is a legendary Runeword created by combining a Bac Rune of Ritual and a Ton Rune of Invocation.
How to Create BacTon
You can create BacTon by adding the legendary Bac Rune of Ritual and the magic Ton Rune of Invocation to a two-socketed Helm, Chest Armor, Pants, or Two-Handed Weapon.

Meteor
Overflow
When BacTon overflows, you receive the Ton Rune's overflow effect (Increased Meteorites Spawned) 1.5 times.
Overflow occurs when your Ritual generates more Offering than required for the Invocation. The overflow effect is proportional to the amount Offering overflows.
