One of the new enchants avaliable in Dragonborn is Chaos Damage. A weapon enchanted with Chaos Damage can deal fire, frost and shock damage at the same time, but the enchantment only works half of the time. Due to the multi-elemental effect, it is boosted by all of the Enchantment and Destruction perks that increase the power of enchantments related to elements (Fire Enchanter, Augmented Shock etc.). In addition, three new Dragon Priest Masks can upgrade your spell damage of a certain element by 25%, Stalhrim items give a bonus to frost enchantments performed on them. Combine them all and what do you get? More magical damage than god himself can give.
