YaxEom is a legendary Runeword created by combining a Yax Rune of Ritual and a Eom Rune of Invocation.
How to Create YaxEom
You can create YaxEom by adding the magic Yax Rune of Ritual and the legendary Eom Rune of Invocation to a two-socketed Helm, Chest Armor, Pants, or Two-Handed Weapon.
Yax - Drink a Healing Potion. (100)
Eom - Reduce your active Cooldowns by 0.25 seconds. (100)
Overflow
YaxEom can not overflow because the amount of Offering you receive from the Yax Rune exactly fills the required Offering of the Eom Rune.
Overflow occurs when your Ritual generates more Offering than required for the Invocation. The overflow effect is proportional to the amount Offering overflows.
