I think I resolved something like this by respeccing the character. Talk to withers and change the class. Not very sure about this, but I do recall how annoying it was. Good luck!

Drop items like healing potions, bombs, etc. with one of your characters. Then use mage hand to throw it by right clicking the dropped items. It’s like having a cheap (but weak) bonus healer shaped like a floating hand

I think it’s great! Just like you I’ve been spending time on getting materials for the potions of speed. It’s also nice that the alchemy system isn’t too much of a hassle to use.

Quite possibly. The gameplay is quite different though. There more conversation trees and choices there have quite some impact on the story and outcomes.

The (combat) system will likely be something you will have to get used to compared to Skyrim and Diablo. It is based on Dungeons and Dragons 5th edition. So you will have to manage your actions each turn of combat in order to get the most out of your characters.

I highly recommend the game, for the reasons above and more.
