CemTon is a magic Runeword created by combining a Cem Rune of Ritual and a Ton Rune of Invocation.
How to Create CemTon
You can create CemTon by adding the magic Cem Rune of Ritual and the magic Ton Rune of Invocation to a two-socketed Helm, Chest Armor, Pants, or Two-Handed Weapon.
Cem - Cast Evade. (50)
Ton - Evoke the Sorcerer's ites, dealing damage to enemies. (25)
Meteor
Overflow
When CemTon overflows, you receive the Ton Rune's overflow effect (Increased Meteorites Spawned) 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.
