I know I used to know what these would get ya, but I have quite forgotten. Is it a heftier treasure chest or does the chest come with nasty monsters? Or something else? And do they sell for a bundle? (Got me a fishing vendor now).

this is what I could find:


There is a 1 in 40 chance that any message in a bottle becomes ‘an ancient SOS’ instead of ‘a waterstained sos’ when opened. Essentially, ‘an ancient SOS’ is a level 4 treasure chest that will always contain a new type of special fishing net called ‘a fabled fishing net’. When ‘a fabled fishing net’ is used deep in the sea, it will spawn a new sea creature called a leviathan. Like other special fishing nets, various sea creatures will also spawn, but in greater number. For comparative purposes, leviathans are equivalent to a paragon blood elemental in difficulty. Like with paragon creatures, possible minor artifact items may be rewarded to player characters who battle and defeat these legendary creatures. Along with typical loot, a leviathan always carries two kinds of ropes and a message in a bottle. It also has a 25% chance to carry a level 5 treasure map.

Thanks Merth!

I went and fished it up and put the fabled net for sale on a vendor. Ended up being a pretty crappy chest but oh well, ya never know.

Thanks so much for the info. It was nice to know I wasn't going to get attacked by anything scary before I fished it up.

I've fished up over 500 mibs and out of all those chests I've probably kept 5 items. Being said the loot out of Sunken Treasure chests needs to be looked at and adjusted for time invested. I mean hell its not even a fast way of farming gold.

I usually just go fish up the ASoS and but the fabled net up for sale for 250k.
