A few (newb) questions

You won't be able to beat the bosses unless you're very well prepared, but you can reach some chests fine (One chest which is straight right once you leave the starting room is very easy to reach). If you have trouble with the Myconian rooms, you can try to kill a few and then go around the rest. They are also easy to outrun since they're pretty slow. The Myconian room from the left of the starting room might be a bit much, but there's no treasure back there so you don't have to worry about it. It's more of a farming spot if you're good at killing them.

Forgot to ask. What is the respawn timer for chests usually, if there is such a timer? I.e. What do I need to do to refresh the items in the dungeon chests, in general?

Most chests, like the ones in Mushroom/Goblin dungeon, refill 3 hours after you've looted them.
