Do rocks have the same range as a Long Bow? Since everything seems to be the same 18m in BG3. Rocks should have a really crappy range and suffer from Disadvantage outside that. They are not actual weapons.

Throwing rocks is more of a joke when talking about combat. There could be a situational rock drop for the Harpies close to their lair but yeah they should sing and swoop down to claw you mostly.

Other than that, I rather like the fight. Using Jump to hunt them down is very satisfying.

But overall, Larian needs to control the urge to give enemies teleport abilities and ranged weapons. Harpies throwing a rock or two is fine, but the Phase Spiders spitting poison and devil pigs jumping over tanks in a tactical chokepoint are not.
