YulEom is a legendary Runeword created by combining a Yul Rune of Ritual and a Eom Rune of Invocation.
How to Create YulEom
You can create YulEom by adding the legendary Yul Rune of Ritual and the legendary Eom Rune of Invocation to a two-socketed Helm, Chest Armor, Pants, or Two-Handed Weapon.
Yul - Cast a Skill with a Cooldown. (50)
Eom - Reduce your active Cooldowns by 0.25 seconds. (100)
Overflow
YulEom can not overflow because the amount of Offering you receive from the Yul 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.
