So my second character hit level 35 today. I'm not sure if it was at level 35 or a few levels before, but the enemies have gotten significantly harder, with huge hit bars such that my Expert-level destruction spells (with 50% off, of course) cannot kill them before I'm out of my 450 magicka. I can kill them with some backpedaling and summoning and the help of my companion, but if I let them get close, I start needing potions, which is something I've been able to do without since level 10 or so. My best chances, frustratingly, seem to be to double-fist my apprentice-level bolt spells to stagger them as they charge me and do so repeatedly until I crit. I can think of several ways to proceed and I would like advice on which is most likely to reap rewards.
A) Focus on element-specific and ultimate-level abilities for my destruction spells - fire/fear, ice/paralyze etc. That'll take four skill points til I max it all out
B) Focus on enchanting - I have almost enough smithing for Ebony and my enchanting is 77. It's been my long-term plan since I started to trade out my wizard robes for heavy armor as soon as I maxed enchanting for the double-enchantment perk.
C) Focus on alteration - My alteration is only at like 35, but I could give up on the heavy armor dream for awhile and work towards the mage armor perk that'd increase my durability substantially so long as I maintain the spell
D) Focus on Magicka - 450 magicka you say?! At level 35?! Scandalous! I should repeatedly put more points into Magicka before I can cast earth-shattering amounts of destruction spells with ease.
E) Focus on Health - Maybe high level fights are going to take awhile as a mage regardless and I should resign myself to being constantly out of mana. The real problem then, is that I can't take anything like what I'm dishing out.
F) Focus on conjuration - My conjuration is at 62, so a good long ways from the top and levels slowly despite fairly frequent use. Nevertheless, maybe I'm supposed to be relying more on familiars and atronachs (i'm already going up the atronach, rather than undead path) and so I should focus on making them stronger and especially achieving the ultimate goal of having two at once.
I appreciate your input.
