Skill: Destruction Perk: Improved Fire damage (can't recall name) Why: This, when added with dual casting and cheaper adept level spells, is quite a bit of fun with fireball. It kills most things quickly, and is especially useful against dragons. I am sure this logic applies to any of the adept level elemental spells/augments.
conjuration, the bound weapon range increased damage, auto soul binding, and auto banishing? just too funny NOT to get especially with the black star from azuras quest, can banish a summoners summon in one swipe, then kill them and take there sould to power my magical stuff
Skill: Destruction Perk: Impact Reason: This allows most dual casting spells to stagger an enemy. Boss/dragon fights are much easier, especially with a companion. Just keep dual casting firebolt while your companion wails away.
Skill: Enchanting Perk: Extra Effect Reason: This allows you to put 2 enchantments on one item. I actually haven't unlocked this yet, but enchanting is very useful once you level it up, so I imagine this will make an very useful skill twice as effective.
