I just hit level 40 in Destruction magic and I don't know what I should pick; Rune Master or Impact? I have spent 4 so far; Novice Destruction / Destruction Dual Casting / Augmented Flames / Apprentice Destruction. I am looking to use Fire as my primary spell group but I use all types. Can anyone help me pick. Don’t want to waste this and wait another three levels trying to fix it. Thanks!
