Telekinesis could definitely use a little love. Currently I can pick up items and throw them at people but wouldn't it be cool if the dagger I picked up actually turned toward the target and stabbed them on release instead of just randomly flying into them hilt first. I also think being able to pick up weaker enemies and toss them about would be pretty cool (force grip anyone?).
-REALLY NEED a mana burn type of spell to use against enemy casters. The "magicka" damage dealt from shock spells is laughable and it needs to deal damage based off of the mana fried (i.e. 80 mana hit, 40 life cut). It can easily be balanced by the fact that it would do less base damage for the cost compared to other spells and is really only for casters. There's currently almost no incentive to use shock over fire in this game.
Wah? How much time have you spent playing a destruction mage? My level 67 still DESTROYS enemy mana bars with high level lightning spells. I almost exclusively use shock just because of how insanely OP it is against casters. Dragon Priests? Ha! The master level lightning spell is a constant stream of lightning doing upwards of 50 mana damage per second.
Detect Life. After Mark/Recall it would probably be my all time favorite TES spells and it needs to be a spell and not just a shout.
It is a spell. There is a Detect Life and a Detect Undead spell already in the game (Alteration). The shout is still superior though due to it's larger range and ability to detect mechanical creatures as well.
Are permanent summons actually permanent (i.e. they don't disappear with use of other conjuration spells)? Haven't gotten that far yet. If not, that should also be a feature.
They are permanent as in you don't have to recast them (they last for ~50000 seconds). Yes they still count toward your limit of maximum summons however personally I think that's a good thing. Playing a necromancer with 50 zombies is not only going to get you trapped EVERYWHERE by the stupid summon AI, but it's probably gonna cause a good deal of lag. If you're hell bent on a small army you can put staffs that summon atronachs/zombies on the corpse of an npc and then raise them with the permanent res. You + companion + 2 permanent zombies + 2 atronach (1 summoned by each zombie) = 6 people. Actually I think your companion can use the staff too so make that 7 lol.
