Alright so I was running around in caves.. for fun.. and I found a way to open chests without having to pull the mobs that block it, or aggro them
This is tested in this cave (Probably working in every caves with that layout)
So you go right there.
Now this require a bit of wall walking, which is super easy.. You get up there
(you can't see but the lil thing become gold which mean u can open it)
Open the chest
???
Profit
I dont think this is a repost, if it is well, im sorry
