OK, two idiot noob questions.

1. How do I equip a quiver? I can't seem to put it anywhere except my hand, but even when it's in my hand it says I don't have one equipped.

2. I'm just in the first well, but healing potions don't seem to do anything. It says "X feels better" when I put one in my hand and ruse it, but I gain no health. What am I doing wrong?

I'm assuming you're talking about Ravenloft - Strahd's Possession.

Left click on the quiver and then left click on the character's upper torso. It should sling the quiver across it's shoulder.

Using a healing potion should restore your health points. A regular health potion may just restore a few hp, so maybe you didn't notice the increasing health bar. Check your numerical hp on the character screen (left or right click on the curved arrow).

I don't think it matters as bows seem to be broken in this game anyways.

Picking up arrows is just a bother. Sniping monsters from afar is a valid strategy, but one should use magical axes and daggers, that automatically return to your hand, for that purpose.

Arrows don't seem to work at all though. I can hit my target every time with rocks, etc, but arrows won't register a hit in my game.
