A big backpack LOK. I'm thinking to step back before the last night (if I still have a saved slot allowing to do that) so I can make more HP before to sleep.
Yeah, now I'm a lot further into the game, I'm using the amulet (not something like the witch's cowl) and charging it up when can, and brewing a lot more potions to take with me to make sure I can restore HP and MP. But I'm playing on Normal not Easy so I guess it should be like that!
