1. At level 17 with destruction at level 52, my most powerful spell is fireballs and of course, I can't use it in confined base because it would blast my follower and my summoner.
2. Conjuration at lv 65 and the nicest thing I can summon without draning my magika completely is Frost Atronach, problem is the thing is too darn big and confined base mean it is render useless, not to mention is hard to cast any offensive spells without hitting it...
3. My only defensive spells is flame cloak which require me to get in close with the enemy and of course wearing robes is not helping.
4. Most destruction spells that you can use without hititting your summon or follower are terribly weak at this point and it took forever and I mean foreva and everrr to level up destruction spell even when blasting fire balls nonstop at enemy.
5. The only way for me actually level up my conjuration properly is abusing the fact that a giaint can't climb rock and just stare at you when you blast it with fireballs. I think is impossible to level conjuration at a proper pace by simply exploring dungeon and fighting random mobs.
To make matter worse, I'm on console which mean no hot keys so it take sometime to switch between spells. I know there ways to solve some of the problem I mentioned above but I still think is pretty annoying how Conjuration aren't exactly useful until the highest level and the more powerful destruction spells aren't ideal for close combats and I'm you all know that there are lots of dungeon. I have no idea how I would continue the game at this point, I was thinking to max out my conjuration first by abusing the fact giaint can't climb rock thing but even if I max it out I still won't have enough magika to summon the more powerful creatures or even if I can is going to drain a lot of magika and I don't like to carry too much potions.
The point is, how do people even max out conjuration or destruction properly cause I really have no idea how to continue on at this point
