The prologue of BG3 is just a 10min incomplete and nearly useless tutorial...
Counterpoints:
Backstory. Imagery. Hints about what the mindflayers are doing (make sure to check out the Illithid tablets).
That stuff isn't important? How about:
Caustic Bulbs are one of the more powerful throwable weapons - the initial acid damage is OK, but they burn really well...
Void Bulbs have the unique mechanic that they can pull enemies around. Given that positioning is so important for combat, this can be powerful. You eventually find arrows and spells that can push, but nothing else allows for more free-form rearrangement.
Spiked Bulbs have low damage (1d4 piercing + 1d4 bleeding for 1 round) but have an AOE that is comparable to oil barrels or second-level spells like Shatter. Against clusters of enemies, they do a heck of a lot more damage than arrows or any first level spell.
The Nautiloid Tanks are your first available exploding barrels and do a lot of damage. You can find one in the crash site, but you can pull a lot more out of the tutorial (you have to play around with inventory a bit to carry that much; they are heavy).
If you fight the cambions, they are worth 120 XP each, far more than most enemies. You can get to level 2 before the crash. The cambions also carry greatswords.
All in all, the tutorial is worth good XP, a solid stock of combat consumables, and several other usable items.
