I start chatting with people (I was bored and was looking for something, ANYTHING to do) and came across a WHM/NIN who assured me she could solo the Coffer Key mobs in Garlaige Citadel so off we went.
We get there, take out about a dozen Fallen Major's and Mage's all the while she's giving me incredible advice on how to make my enfeebles more effective when she pulls and says "Last one. I gotta go. Sorry." I told her I was just happy to have gotten to do SOMETHING when the key drops off that mob. We joke around about how she should say "Last mob, gotta go" before every pull next time and she leaves. I asked my LS if they could assist me in a Gate Breach after Besieged and they agreed so I went off to Valkurm Dunes to offer Raises to people.
Naturally no one needed a raise. So Besieged was a total failure and the LS decided to take a break and I decided "I'm gonna go to Jeuno and shout for a Gate Breach party." So I did and apparently there was some confusion because I had to tell at least five people that all I wanted was to get to the Coffer spawn points.
After a couple hours a few more people in need of Coffer keys and other AF-related activities popped. We discussed making an alliance, hit up as many level 75 friends as we all could (I couldn't find anyone) and off we went.
First to Garlaige Citadel to pop my Coffer, farm two keys, then pop those two Coffers. It was funny, too. I pop my Coffer (Behind Banishing Gate #3) then a key drops. RDM won the lot so he joins the Gate Breach team and 30 minutes later pops his Coffer then two keys drop so we pop the last Coffer and head off to The Eldieme Necropolis for another Coffer and two Bells (I already had mine. It was a gift from a friend that left the game.) Took us about 90 minutes to do that thanks to a Thief we picked up with TH3.
The WAR, who needed the Coffer for his AF hands, gets the rest of the quest and we grab a couple more level 75's (WHM and BLM) then head off to the Northlands for WHM AF3 and Dark Spark.
Once we assemble at Fei'Yin we go over the plan: PLD is main tank, WAR is backup and SATA partner, the BLM nukes, and the three WHM's heal. First two fights were textbook. No joke, we could have recorded them and put them on YouTube as an example of how to win WHM AF3. Then it was my turn. That's when the NM decided to go all out! The consensus was that my NM had Wheaties for breakfast. Spamming AM and Dimensional Death and to make matters worse, the Thief D/C's in the middle of all this! With him gone damage goes down big time, but the NM calmed down after that. At 1/4 health he catches his second wind and we're freaking out. PLD and WAR pop 2 hour's and before the PLD dies the NM's at a sliver of health so the BLM does an Elemental Seal + Burst II then me and the other 2 WHM's Holy and the f***er's STILL ALIVE!!! He has no discernible HP BUT HE LIVES!!!
After that massive spike in hate he slaughters us mage's leaving only the WAR alive with Utsu shadows falling fast so he starts screaming at me to Reraise so he can kill the NM and not get the drop, I'm screaming at him to get that thing away from me and I will then the Thief reappears, gets behind the mob and activates SATA so the WAR invites him, he does a Shark Bite (Even he was puzzled as to why he popped with 300% TP) and FINALLY the S.O.B. makes his little speech and I Reraise, lot on the mask, and heal.
After everyone has been revived and weakness has worn we decide to kill Dark Spark and hope he had a Lumberjack Breakfast

So Dark Spark...Only issue we had was his Bio spamming could not keep up with four people using Erase (Dark Spark uses Bio, WHM Erase, DS uses Bio, etc) so with that WAR got his flame, we all said our goodbye's and us WHM's head off to claim our AF Body pieces.
So yeah, I came real close to not getting mine, but I did so its all cool. Now I just need to gain 2 levels to wear it then go to Beadeaux, get the Coffer, then find some nice person to kill Dark Spark for me and I will be done with my WHM AF.
