No. It does need more power. I'm fed up with people saying its just fine. Its not. It shouldnt take a million hits to kill something. FYI I don't svck. So stop making false accusations. And people have already done the math. You can't argue with numericle fact.
Okay, I dual cast incinerate to do 220 damage. I can use a +120% potion to do ~500 damage. How strong do you want it to be, enlighten me?
With that data I can kill an ancient dragon (one of the most difficult, highest health enemies you come across) in 28 dual incinerates, and 12 incinerates with the potion. That to me is very strong, you couldn't match that without exploiting the system with archery.
Some good points there, I totally agree with the clothing-alteration armor problem. There needs to be a benefit, I do it anyway as its more fun and challenging, but there should be a benefit.
Edit: The archmages robes are unique though, they provide very useful enchantments you can't match on armor. There needs to be more unique non-armor apparel that is useful.
I use master spells all the time, they key is to use the become ethereal shout or use sneak/invisibility. Thats how I cast my master spells mid battle, use become ethereal and walk up to them, charge up mass paralyse and floor them all. Then unleash blizzard followed by fire storms, which do a lot more damage than stated.
I do wish there was a quest, maybe if you had all the master spells available, from winterhold that allowed you to cut the charge time down by half and so you can't be staggered whilst charging.
The magicka cost is ridiculous I agree, I use ~92% magicka reduction for destruction (which I made sure wasn't to much), this allows me to cast a good few spells but not endlessly stagger the enemy. I shouldn't have to do this myself though to be honest, I should be able to use destruction without enchanting. Some people just go with 100% reduction, I don't find it that fun, but others do.
