First off, there are four types of play styles that use Spells. These are the "Pure" Mage, the Battle Mage, the Spell Blade, and the Night Blade. The "Pure" Mage is as the name suggest- a character that relies purely on the Arcane Arts. The Battle Mage is a Mage that uses physical attacks and most of the Arts. According to Elder Scrolls lore, Battle Mages don't wear armor. Instead they use the Arts to shield themselves from physical harm with magical spells. A Spell Blade, on the other hand, used armor- Heavy Armor. With a weapon in one hand and a Destruction spell in the other, these Mages jump into the fray of battle. The Night Blade is the opposite of a Spell Blade, wearing Light Armor, using stealth to stay hidden, dealing critical damage from the shadows, setting Destruction traps in the form of Runes, and using Illusion to become unheard, unseen, and control the mind's of their foes. In this entry I will be covering the Pure Mage and the Battle Mage.
The Pure Mage and the Battle Mage are almost opposite of each other, in a way, that one deals damage different then the other. Pure Mages use Destruction and cause no physical damage while Battle Mages only cause physical damage and don't use Destruction. To confiscate for this, the Pure Mage uses Conjuration to reanimate fallen Warrior type enemies to fight for them, dealing the physical damage the Pure Mage lacks, and the Battle Mage summons Atronachs, dealing Destruction damage the Battle Mage lacks. This makes the Pure Mage a Necromancer and the Battle Mage an Atromancer. The recommended races are High Elf for the Necromancer and Breton for the Atromancer.
Now that the extreme differences of each class are out of the way, it's time to explain the subtle similarities. Both Mages will use Alteration, Conjuration, Illusion, and Restoration, however, in different ways. The Necromancer uses Alteration mostly to protect their magicka pool with Magic Resistance and to Paralyze enemies. The Atromancer uses Alteration to protect themselves from physical damage. The Necromancer uses Conjuration to summon the dead to fight for them while the Atromancer uses it to summon Atronachs and Bound Weapons. Both Mages use Illusion to control the minds of their enemies and also to get themselves out of tight situations; being a "glass cannon" and all. Both use Restoration to heal themselves and to keep the undead off them.
Now Enchanting is different. The Necromancer will use Enchanting but the Atromancer does not. This is due to the fact that the Necromancer will need the custom gear as the Atromancer will not. Also, the High Elves gets a bonus in Enchanting as the Breton does not. However, the Breton does get a bonus in Speech allowing them to get their hands on what they need at lower prices and a bonus in Alchemy allowing them to brew potions for profit or to boost their Arcane potencies.
Another note: Necromancers will Dual Cast everything while Atromancers Dual Cast nothing.
In my next post I'll be covering the other Hybrids: the Spell Blade and the Night Blade. If you learned something from this guide, have anymore in-depth questions, or would like me to just send you the specific specs to each build, feel free to leave a comment.
