Event jewelry always has more total power than regular jewelry. A completely unleveled event ring typically starts with 1200 total power (stats are distributed between atk and def). However, a +10 warrior ring starts with 1000 total power, all in atk.

Or earrings are the better example. Event earring have nearly double the stats as normal earrings but it is all def.

Whaleship is based off total power - should I be using event jewelry? Or should I be attempting to maximize the atk stat?

in short, is "total power' for whaleship also a little misleading in that I should value the atk stat more than the other stats?
