LithGar is a legendary Runeword created by combining a Lith Rune of Ritual and a Gar Rune of Invocation.
How to Create LithGar
You can create LithGar by adding the legendary Lith Rune of Ritual and the magic Gar 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)
Gar - Gain 2.5% Critical Strike Chance for 5 seconds, up to 25%. (25)
Overflow
LithGar can not overflow because the amount of Offering you receive from the Lith Rune exactly fills the required Offering of the Gar Rune.
Overflow occurs when your Ritual generates more Offering than required for the Invocation. The overflow effect is proportional to the amount Offering overflows.
