Baldur's Gate 3 - Magic Missile Build vs Dragon Ansur on Tactican Solo

Build Require Evocation Wizard 10 to add Inteligence Modifier to each Missile and I took 2 lvls of Sorcerer just to convert lowier tier spells to Sorcery Points and those SP to 5th level spell slots (cant 6th). I know this is not efficient way to play, but cmon lets have some fun :)
Feats: Just max INT
Its not min maxed build. IDK what other items works well with MMs besides The Spellsparkler Staff, Psychic Spark Amulet and Callous Glow Ring.
Curriculum of Strategy is a unique scroll hiden in Lorroakan Tower (Sorcerous Sundries). Wizard can learn this spell to have it in the spellbook. Its a bit better than MMs, but you can cast it only once per short rest.
Dont need to have full Illithid Powers Tree, just Mind Sanctuary to cast MMs on Bonus Action and Perilous Strikes to make enemy Vulnerable to all damage. More points in the Tree makes Cull the Weak passive better - "When you bring a creature down to fewer hit points than your number of evolved illithid powers, it dies and all nearby creatures take 1-4 Psychic damage".
