Baldur's Gate 2 - Sorcerer solo Ascension Final Battle Part 1 [Insane Difficulty]

I decided to play BG2 again after finishing BGEE. This is the first time I solo a sorcerer through Ascension. =) In case anybody is wondering. All my gameplays are done legitimately under the level cap without any character editing. All the equipments I have are legit in-game items.
