Illusion is the most powerful magic in Vanilla Skyrim. Make sure you have the ability to Dual Cast your Illusion spells; after that everything should be a cakewalk. The reason I say this is because, once you have a few points in Illusion, there should be NOTHING you cannot calm/fear/fury. I made a brand new character, a mage, and took him down the path of pure Illusion magic. He is currently level 11, and can calm/fear/fury a Giant, a mammoth, any and all bandits, and anything else in the game basically. (minus dragons, of course) If you're looking for fighting tips, here you go: 1. Make sure you've purchased Calm/Fear/Fury. 2. Hotkey all 3 spells. 3. When entering a fight, pick out the strongest enemy you see. (for example, the Bandit Chief among two other bandits) 4. Dual Cast FURY on him, and avoid any interaction with ANY of the other enemies until; 5. The enemy you cast FURY on begins attacking his teammates. 6. Sit back and allow them to kill each other, feel free to refresh FURY on your main target (same thing as #4, avoid any confrontation with the enemy until he begins to ignore you and fight his teammates) 7. When the only enemy left standing is the Bandit Chief, simply cast CALM on him. 8. From here, you have many options---FEAR him so he won't fight back as you attack him, CALM him to regenerate mana quicker, or anything else you want to do. These are some of the things I do when fighting using Illusion. Just make sure you have the right perk points in Illusion. You need all the perks that allow you to cast on higher level enemies, as well as Dual Casting. Dual Casting is key, and this is why---If calm only works on a level 9, then when DUAL CASTED it will work on level 20. (2.2x more than the original cast) Hope this helps.
