Larian doesn't really care about consistency.
They took what they find cool everywhere in D&D and the FR, change,mix them and add their own touche everywhere and... that's BG3.
This game is absolutely inconsistent in regards of the FR and D&D...
If you're a random low level from the surface that jump in a hole and fight with creatures in the underdark... You die. End.
Drizzt almost die there many times even if he's a powerfull native that had years of rude training in Menzoberranzan (and he didn't encounter overboosted minotaurs).
And yes those companions story...
They all lived totally WTF things but yea... Still level 1...
But don't worry, "that's the tadpole"
And I don't remember that you can dip your weapon in fire to have a +1D4 fire damage weapon in the FR, but that's another point.
