I made a wizard with minimum Intelligence, and I do not plan to even get the headband. There are so many great wizard spells that don't require high Int to work. All I need is Jump, Expeditious Retreat, Feather Fall, Fog Cloud, Sleep, Magic Missile, False Life, Grease, Mage Armor, Invisibility, Mirror Image, Misty Step, eventually Haste, etc.
Not sure it will really get you far in a fight. Magic Missile isn't all that good in the long run. Unless you are building a melee fighter.
This. Magic Missile is reliable, but the damage is very minimal compared to other direct damage spells you get. By pumping up your Int you will also have a higher hit percentage with those spells, making the reliability of MM comparatively less significant once your character’s magic attack bonus has increased.
That really isn’t a great build in the long run (fine for EA). But you do you, though.
Personally I don’t see the fun in playing a character who sucks at doing the thing they are supposed to do. I will impose artificial challenges on myself in other games in order to make the gameplay more intense, but that is only when the game can still be beaten with enough attentiveness and skill. BG3 is very reliant on RNG, so by handicapping a character’s primary skill you are just reducing your odds of your character successfully completing actions. So then you are just mitigating the bonuses you receive by positioning your characters correctly and wearing gear that increases your success odds, which seems weirdly counter-intuitive. At least that is how it seems to me. That just strikes me as frustrating instead of fun.
But again, you do you.
