That race is better as a regular spellcaster, thanks to having the highest Magicka multiplier, but can work well as an enchanter as well. Altmer is here only because they start with higher Enchant skill value and have high Intelligence.Thanks to that they have an easier time when trying to create enchanted items. This is also one of the races that start with high Intelligence. Breton has a natural resistance to magic (50%) and has daily power that is really good early game: Shield (60 points).One bad thing is they start with low Intelligence, which makes it harder to be a successful enchanter early on (matters mostly when trying to create enchanting items). On top of that, they have high starting Strength and Endurance, so they have higher base health, which is always helpful, and can carry more loot. Nord has natural immunity to frost (100%), resistance to shock (50%), and two somewhat decent powers that might help the early game.There is an easy way to obtain 100% resistance to fire and thus making that character immune to this kind of damage (lava can still hurt). On top of that, they have the racial ability of Sanctuary, which is really helpful throughout the entire playthrough.

Dunmer has a natural resistance to fire, from the very beginning, whole 75%.
