I always loved the dungeon boss-specific achievements from World of Warcraft, as I thought they added additional, completely optional challenges to dungeons for completing them in interesting ways or by handling additional difficulties through the boss fight.
I think incorporating these to boss fights through FFXIV’s dungeons would allow for some great replay value for dungeons, as well as something for small groups to challenge if for nothing more than an achievement and personal satisfaction.
I came up with a few example achievements for a few current dungeon bosses:
Sunken Temple of Qarn (Hard)
Defeat Vicegerent To The Warden after transforming each of your party members into a mummy at least once.
Out of Sight…
Defeat Anantaboga without any party member being hit by Imminent Catastrophe.
Stop… Zombie time!
Defeat Siren without allowing her Zombie Storm Sergeants to grab their targets.
Drawing a Bead
Brayflox Longstop (Hard)
Defeat Gobmachine G-VI without killing any Illuminati Snipers.
Demons, Orbs, and Doors! Oh My!
Lost City of Amdapor
Defeat Diabolos without any party member being hit by exploding orbs.
Some are easier than others, so you might see one while queing via duty finder, while others would need to be sought by perhaps forming your own group beforehand.
What do you think?
