FeoXan is a legendary Runeword created by combining a Feo Rune of Ritual and a Xan Rune of Invocation.
How to Create FeoXan
You can create FeoXan by adding the rare Feo Rune of Ritual and the legendary Xan Rune of Invocation to a two-socketed Helm, Chest Armor, Pants, or Two-Handed Weapon.
Feo - Become Injured or Crowd Controlled. (Cooldown: 10 seconds) (1000)
Xan - Your next Skill cast will be a guaranteed Critical Strike and Overpower. (800)
Overflow
FeoXan can not overflow because the Xan Rune does not have an overflow effect.
Overflow occurs when your Ritual generates more Offering than required for the Invocation. The overflow effect is proportional to the amount Offering overflows.
