I'm a little dissatisfied with only being able to enchant your weapons with either fire, ice or storm (electricity) damage. Considering the amount of undead in the game, I think adding sun damage as a fourth damage type would be great. Not only for variety's sake, but for it's correlation with the Templar class. If it already is in the game, I hope it doesn't appear just as a spell/skill or on pre-enchanted weapons like it did in Skyrim. Specifically, I want the ability to enchant an item with this weapon type.

Depending on how you look at it, restoration magic is a damage type.

Unless it has some ritualistic meaning, it really doesn't matter. It is all focused energy damage after all, fire works pretty well, or lightning. I don't even think they should be all horizontally scaled. A single bolt of lightning should take out most opponent, sure make it tough to cast with a ton of resources used. Fire spells could work very well for spreading dots and covering aoe.

Im okay with sun damage being added in game however, i wouldnt want it to be something that is commonly enchanted on weapons. This can be in the form of Unique weapons or skills.

We can also have it as a 24 hr spell only like in Skyrim in the form of the Sun Stone.

Why would you need a separate element of destruction magic when fire could potentially do the job instead? The Sun is after all a massive globe of fiery matter.
