Really wish there was an expensive full restore gp cordial.
Some fish like cinder surprise require too much gp to prep, if you were busy irl or other in-game activities and didn't arrive 20 min earlier you simply won't have time to prep.
This is mainly why I find fishing to be such a garbage activity in this game, it's a black hole that doesn't let you do other things in-game, hyper gp expensive preps in combination with ints not allowing you to leave the zone is unfun and it will always be unfun.
