WithThe Arcadion (Savage)raid tier making its debut inFinal Fantasy XIV, there’s been plenty of chatter around encounter design and what makes some of these fights really shine. Amid the discussions, you may see the term ‘door boss’ come up fairly often, but what does that mean?
For anyone who isn’t deep intoFFXIVterminology, the term can be a little confusing. In short, a door boss is the first boss in a two-phase duty. Defeating this first boss creates a kind of checkpoint in the middle of the fight. When your enemy’s HP hits zero, there’s typically a cutscene and a new boss form.

Is this annoying? Sure, but it’s got its benefits. If the party wipes from this point on, you’ll start the fight over from the middle as long as you don’t leave the duty or run out of time. Should you exit either way, the party must start the fight over from the beginning and defeat the door boss again.
