Andor's Trail

I slept in Lodar's bed, and now I can't buy supplements to continue the cave

my game is a single save, and when I die I wake up in Lodar's bed

I would like to somehow return to the city to buy supplements and continue the game.
As it is, all I can do is die infinitely

I recommend killing as many of the ghost things as you can, then return to bed before you die. Repeat that process until you level up / farm whatever valuables they drop so that you can buy potions.

There is a "shortcut" back to the rest of the game, but while it is shorter, the aggressive monsters are not easier. If anything, it might be easier to survive by taking the longer route.

Since I am not a developer, I am not able to add an easier shortcut to the game in order to help players like you.

Therefore, I just recommend you farm the monsters for xp until you are able to survive getting back out of the area.

Regeneration is a valuable skill, so, if you manage to farm enough exp to level up, that skill may help to get out of the cave without too many potions.
