BacTun - Selachian Volatile Powder

BacTun is a legendary Runeword created by combining a Bac Rune of Ritual and a Tun Rune of Invocation.

How to Create BacTun

You can create BacTun by adding the legendary Bac Rune of Ritual and the magic Tun Rune of Invocation to a two-socketed Helm, Chest Armor, Pants, or Two-Handed Weapon.

Bac - Travel 5 meters. (50)

Tun - Invoke the Rogue's Stun Grenades, Stunning and dealing damage to enemies. (100)

Overflow

BacTun can not overflow because the amount of Offering you receive from the Bac Rune exactly fills the required Offering of the Tun Rune.

Overflow occurs when your Ritual generates more Offering than required for the Invocation. The overflow effect is proportional to the amount Offering overflows.
