I have to defend gale. I really much like this character. I think the voicing is brilliant, i like his story, i like the way he talks and behaves.
I only take mechanical issues in him consuming only the strongest of items, that you loot in the story. Really hurts giving him a helmet that can turn you invisible.
You should be able to feed him with generic magical items that you either find or buy. Got a random +2 club from a gnoll that im not going to use anyways. +2 enhancement is pretty strong magic in D&D, especially on low levels. Giving it away is because you want to help him out feels like a fair price to pay.
giving up super special named relics on the other hands just feels punishing.
also, why is it, that im level 4 and have more magical stuff than most shops in big cities have

like seriously, level 4 and having easily 20+ magic items plus a s-load of elemental arrows, scrolls and potions? Yo what? magic items are supposed to be rare. I think being level 4 in BG1 i had perhaps 2-3 generic +1 weapons and thats it. In BG it was an actualy thing to kill ankegs to have an ankeg armor crafted wich was essentially a non magical plate.
