CemGar is a magic Runeword created by combining a Cem Rune of Ritual and a Gar Rune of Invocation.
How to Create CemGar
You can create CemGar by adding the magic Cem Rune of Ritual and the magic Gar Rune of Invocation to a two-socketed Helm, Chest Armor, Pants, or Two-Handed Weapon.
Cem - Cast Evade. (75)
Gar - Gain 2.5% Critical Strike Chance for 5 seconds, up to 25%. (25)
Overflow
When CemGar overflows, you receive the Gar Rune's overflow effect (Gain Multiple Stacks) 2 times.
Overflow occurs when your Ritual generates more Offering than required for the Invocation. The overflow effect is proportional to the amount Offering overflows.
