I'm having two bits of trouble. First, the simpler one: what's the big deal about Illusion? Many on this forum have claimed that it's outright the most potent, tide-turning school of magic out there. Being that even my pure mages don't focus on Illusion (I prefer Destruction and Restoration most), I want to know what's so great about it and why I should try it. As it stands, I don't even plan on having my stealth characters invest in it, but I'm open for discussion and want to learn about it.
Secondly, I'm having a very hard time trying to figure out an ideal battlemage build. This problem is a little more complex.
See, I've got a dual-wield Khajiit. I focus on four skills and only have perks in those skills: light armor for defense and maneuverability (the wind walker perk is amazing!), smithing for obvious reasons, alchemy as my main means of recovery and to augment damage as well as status my enemies with paralysis (I love how easy that recipe is), and, obviously, one handed, with a focus on swords for DPS since they swing fastest and can have an increased crit chance, which is more balanced than axes or maces--not every foe can bleed and not every foe wears armor. I absolutely love him. And in case you're wondering, shouts and companions work as my ranged damage dealers, particularly against flying dragons (going to get Dragonrend soon, so I have even less to worry about). I could go on and on about my wonderful Al'Tair, but I'll only speak about what's relevant to my mage build.
So I noticed early on that I can and am getting great utility out of my skills because I'm focusing on only four of them; it gives me pretty good variety while at the same time not spreading me thin. My mage is somewhat similar, going through the game using only Destruction and Restoration, but this was more of something that I noticed rather than something I planned.
My question is, how do I make an ideal battlemage? I'm really eager to do so, and have already tried and failed (in fact, my first two characters were Breton and Dunmer battlemages that ended up terrible). I don't know what to do since there are so many viable choices, and I worry about spreading my skills thin.
First, offense. Obviously, I'm going to need one handed and Destruction, otherwise I'll just feel like a mage in armor or a paladin. But after that, it gets complex.
Secondly, crafting. Ideally, I want smithing AND enchanting, but there are problems with this. To best utilize smithing, I should invest in an armor tree as well--I think it would be a waste to smith just for weapons, as well as a waste to not improve weapons at all. Smithing must stay, and I'll drop enchanting for it if I have to.
Next defense. Armor or Alteration? With paralysis, magic resistance/absorption perks and other fancy things, it seems the obvious path, as well as enabling me to wear good mage robes (my current inspiration for a battlemage is actually that Dunmer in Thalmor robes with the Deadric sword during the loading screens), which would also be better than armor if i have to forego enchanting. However, armor has the advantage of constantly improving three of my skills--the armor skill itself, smithing, and my recovery skill (more on that later)--with very little micromanagement, unlike Alteration, and it wouldn't drain my precious Magicka pool (whose increases have to be shared with the other two attributes for an effective battlemage). On top of that, I can use high level armor as soon as I can find or forge it not only without penalty, but to my ADVANTAGE, which is the complete opposite of any magic school. If I use armor, it will likely be heavy; anyone is welcome to try and convince me otherwise, and we'll see what happens.
Finally (and probably fourthly, unless I have smithing AND enchanting), recovery. Restoration seems obvious, but that's another drain on my precious magic. With alchemy (something I never used in Oblivion but recently learned to love, since I refused to use magic with my Khajiit but still needed a way to recover), I can recover quickly and easily without interrupting battle (sounds cheap, I know), and it has many, many more advantages. I can recover my much-needed stamina without need for a perk while also recovering health and go right back into my power attacks or running, it can make me a lot of money (which Restoration obviously can't do), and I can status the crap out of my enemies; other than paralysis, I have little need to status with my Khajiit, but if someone uses melee AND magic, there's much use in weakness to magic/fire/etc. poisons. In fact, the advantages are too many fold, so I think I'm pretty set on having alchemy as my means of recovery instead of Restoration. If you think I should have Restoration, make your case, and make it a strong one.
An enchanting note: enchanted weapons will necessitate that I learn Soul Trap from the Conjuration tree, which is not something I want to invest in, for recharging. That, or I'll be in constant need of soul-trapping weapons. Also, if I have enchanting, I pretty much need an armor skill to make the best of it, which would mean several things: I'll be invested in all three crafting skills already (which both spreads me thinner and is overly powerful), I won't be using Alteration because of that, and even though I'd have some investment in Conjuration, it wouldn't be much since I'll be smithing my own weapons and want to go into battle sans summons. Overall, I think enchanting is out of the equation, which bothers me a little since it feels like the most battlemagey skill of all to me.
So there you have it, my whole dilemma. Beyond that, I suppose I could be a full mage who augments his offensive capabilities with one-handed weapons (but then I'll want smithing to improve them better...then armor...), or, more feasibly, I could be a full warrior who uses Destruction as an extra means of offense and Restoration to heal.
Please help me!
