LithEom is a legendary Runeword created by combining a Lith Rune of Ritual and a Eom Rune of Invocation.
How to Create LithEom
You can create LithEom by adding the legendary Lith Rune of Ritual and the legendary Eom Rune of Invocation to a two-socketed Helm, Chest Armor, Pants, or Two-Handed Weapon.
Lith - Stand still while fighting for 0.31 seconds. (25)
Eom - Reduce your active Cooldowns by 0.11 seconds. (100)
Overflow
LithEom can not overflow because the amount of Offering you receive from the Lith 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.
