LithMet is a legendary Runeword created by combining a Lith Rune of Ritual and a Met Rune of Invocation.
How to Create LithMet
You can create LithMet by adding the legendary Lith Rune of Ritual and the magic Met 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)
Met - You leave the Necromancer's Desecrated Ground behind you for 3 seconds, dealing damage to enemies within. (100)
Overflow
LithMet can not overflow because the amount of Offering you receive from the Lith Rune exactly fills the required Offering of the Met Rune.
Overflow occurs when your Ritual generates more Offering than required for the Invocation. The overflow effect is proportional to the amount Offering overflows.
