I want to learn all spells as well! Wizards have the most spells in the game i think and that makes sense, and I love the spells compared to other games. They are often seen as damage dealer or elementalist which is fine by all means but magic to me is more than dealing damage, it is also fun. That is why polymorph is one of my favorite spells as well as the Arcane Lock/Knock, Otto's Irresistible Dance etc. Because in other games it is just Fireball! Ice Spear! go do damage. Magic is so much more than that, and I think BG3 has done amazing job with that.
But still I find myselff casting damage dealing spells. So I am looking for a creative build like, casting grease and firebolt creates a fire surface! or Reduce someone and then throw him etc.
Well it seems I going to try Haste for sure!
Any other ideas? ^^ <3
