CemLum is a magic Runeword created by combining a Cem Rune of Ritual and a Lum Rune of Invocation.
How to Create CemLum
You can create CemLum by adding the magic Cem Rune of Ritual and the magic Lum Rune of Invocation to a two-socketed Helm, Chest Armor, Pants, or Two-Handed Weapon.
Cem - Cast Evade. (75)
Lum - Restore 2.5 Primary Resource. (5)
Overflow
When CemLum overflows, you receive the Lum Rune's overflow effect (Increased Resource Restored) 14 times.
Overflow occurs when your Ritual generates more Offering than required for the Invocation. The overflow effect is proportional to the amount Offering overflows.
