Getting some of the best owner perks in Dead or Alive Xtreme 3 requires a lot of patience. Acquiring them all requires progressing until owner level 110, which is a whole ton of work slaving for those capricious ladies.
Luckily, summer is the right time for bikinis, and Koei Tecmo has an event going on. Until August 31st, every vacation you complete will earn you 5 times as much owner experience.
Unfortunately the effect applies only to end-of-vacation experience, and not to all experience earned. Yet, it’s much better than nothing. It won’t instantly level you up to 110, but it’ll certainly help.
