past insanity 4ish range of the dark sea, pretty much every chest becomes golden or silver, and there’s a LOT of them too
the chance of a 1 in 60 is ~1.67%, which sounds low, but remember, there are tons of those chests in the deeper areas. get your warding 6 build and stock up on invis potions
Only issue I see here is that we’re like coughing babies in Insanity 4 right now, but if you don’t care for Dark Sealed Chests, you could probably get a bunch of scrolls to sell.
invis potions completely nullify any danger in the dark sea (mostly)
the only issue is farming jade pearls which is a pain, id say 30 jade pearls (60 invis potions) is good enough to last you a while, and save some of the pearls to make silver invis potions which last longer
That happened to me with a Giant White Eyes. I was just getting a few from a structure near Rubica when it came out of nowhere and one-shotted me I didn’t go underwater again for a whole week
