^ This isn't a reliable reference number. It take quite a bit luck to do even in easy in the extra part of any random event for ships with Lv 50. I'd say target at lv.30 (or first kai level) only if you're already into event but then you find out you don't have a certain ship that you need to use, in that case probably you can capture one on the fly and make it kai 1 on spot with maxmod.
