There are two different event CEs. You get golden catches the carp from the damage point ladder, and wandering tales from the shop using gourds + 1 from damage ladder. MLBing wandering tales is very useful, as it’ll bring your bonus to 300%, while MLBing carp just lowers your damage unless you’re freeing up space to farm extra gourds.

The 3rd one lets you use more bonus CEs and is easier, so it’s a better place to get gourds. It also costs less BP and is significantly easier. The 4th is the best place if you’re trying to get damage points ASAP, but I’d say the 3rd is better all around unless you’re specifically aiming to get damage points ASAP.
