Since I console-d my level to always revert back to six, my available perk points went through the roof, and so is my magicka and health points
The Setup:
100 in Destruction Damage, Alteration Armor, Restoration Ward, Illusion Not used, Conjuration ot used
All perks taken. Especially:
Augmented Flames and Destruction Dual Casting Maximum Damage
Mage Armor and Alteration Dual Casting Maximum Armor
All magicka cost reduction perks
Player level: 8
Health: 1030
Magicka: 430
Robes of Minor Destruction (12% Destruction cost reduction), Leather Bracers of Archery, because I can (about 20 armor points)
Saarthal Amulet (3% Magicka cost reduction)
The enemy was a Draugr Deathlord in Saarthal (how the boss can be a Deathlord is beyond me, I thought it'd be lower than that)
What I did:
Casted Dualcast Ebonyflesh, 100 armor points for 198 seconds
Put up Steadfast Ward (sorry, I haven't gotten the more powerful version), around 60 points armor rating? I put 'em up all the time
What happened:
Well, with 1030 health points and Ebonyflesh (with Mage Armor) and a Steadfast ward, I thought I can stand ground for quite a few hits
Turns out I couldn't stand more than 5 hits.
Of course, I purposely did not try to run away, but considering the amount of health I have, this is a bit discouraging
Tried to dualcast Incinerate. Works wonders, but with that I've lost quite a bit of magicka. Dual casting incinerate causes me to lose around 1/3 of Magicka bar
With 430 points of Magicka, that translates to around 150 points, even with Expert Destruction perk. On a side note, I didn't try to incinerate the Draugr Deathlord, but I did try to Dualcast Incinerate the Gauldur in Saarthal, it was a one hit KO, but since I was at level 8, I don't know how it should've worked
Another side note is that Steadfast Ward immediately falls before the said Gauldur's ice magic. I assume it's frostbite (because it can cast the magic continuously), and since frostbite is a novice spell, I was disappointed
What I think:
Destruction without a lot of Potion of Vigorous Magicka, or powerful Destruction enchantment, is truly not feasible. It does quite a good job at dealing damage by itself, but the magicka cost is certainly disouraging. Even 50% cost reduction does not help
Alteration can provide a decent amount of armor points, but it is simply useless against boss enemies, you'll need another damage sponge for that. Especially for mages that had to divide points in Stamina, Magicka, and Health. 1030 points of health is beyond reality in a vanilla game, and even with that I can't stand much beating. Banded Iron Shield and Shield Wall works much better at absorbing damage
