CirGar is a magic Runeword created by combining a Cir Rune of Ritual and a Gar Rune of Invocation.
How to Create CirGar
You can create CirGar by adding the magic Cir Rune of Ritual and the magic Gar Rune of Invocation to a two-socketed Helm, Chest Armor, Pants, or Two-Handed Weapon.
Cir - Cast the same non-Channeled Skill 3 times in a row. (50)
Gar - Gain 2.5% Critical Strike Chance for 5 seconds, up to 25%. (25)
Overflow
When CirGar overflows, you receive the Gar Rune's overflow effect (Gain Multiple Stacks) 1 times.
Overflow occurs when your Ritual generates more Offering than required for the Invocation. The overflow effect is proportional to the amount Offering overflows.
