Is It Possible To Extend The Abyssea Time Without

Hi guys i want to fish in abyssea, and i want to know, if its possible to extend the abyssea time i can fish inside?

save up max time, get 3 more stones, when you get the 10~ min mark go turn the rest in i guess

other than that i dunno other than from killing exp mobs x.x

Can buy an abyssite for 3k? cruor that gives 3 minutes per stone.

Buy a Ivory Abyssite of Sojourn from any Cruor Prospector (adds 3 mins per stone).

If you have a few days worth of stones stored, you can leave with 2mins left if you wish, then return get another 3 and continue.

As for extending your time, the fish you caught probably don't snack on Stone Fragments, so you're out of luck there.
