MHP: Defeating the Legendary Black Dragon, Fatalis

The final boss. Ominous-looking.

Ominous and cool.

You just attack from this rear-left position. It keeps crawling against the wall. The rest is up to luck. Since this quest is meant for multiplayer festivals, is there some kind of special treatment for solo players?

There are phases 1 through 4, and dealing 1/4 of the total damage in any of them four times results in a defeat and clear. So I guess I should have just kept doing the easiest one, phase 1. I cleared phases 1 and 2, failed at phase 3, but then switched back to phase 1 and cleared it.

With this, I consider MHP beaten and finished. Time to play a bit of Yakuza 2 and then move on to MHP2!
