Dawn

After the 8-3 battle and the two cutscense (the latter is really the start of this, as it reveals the final boss powering up for the apocolypse), you simply head to the bottom of the main elevator and into a new zone room which has the final BCNM entrance.

There's a cutscene at the entrance to the BCNM, and after you watch that you can touch the area for the BCNM entry choice "Dawn."

This battle is rather easy compared to the rest of CoP. How easy? We beat it on the first try with Pld Whm Smn Rng Drg/sam Thf/nin. Sure we used some ethers and hi-potions, but we didn't have refresh and only had one provoker.

Yappari Kero-chan Check!

1) Part 1 of this fight is easy, don't waste any 2hrs on it. You have just enough time to full rest before the NPC starts the second part.

2) You have two NPC allies, a flying one and a non-flying one. If the flying one dies, you lose. You can cast raise on the non-flier. In fact, it is recommended that you not even heal the non-flier, just raise 1 them when they die.

3) You can let the non-flying NPC ally tank most of the time, also, the NPCs do most of the killing too. In our case our Pld the entire fight, the important thing is you don't want the flying NPC ally to tank - they're out of your healing range. Smn pet can also tank most of this battle, or so I read. Astral for the attack ability isn't worth it.

4) Boss has heinous, crazy abilities - Quiesence - aoe silence that cannot be removed (I think you can spam echos 25% chance maybe?) and lasts 2 minutes, and Oblivion - aoe "you have no job abilities at all (no WS neither)" that lasts 1 minute. Also, it has "no magic damage" and "no physical damage" abilities - they don't last too long

5) When Quiesence hits, kite it around the outside (the arena is quite large) and regen mp. We actually kited it for most of the battle to avoid Meteor and reduce the number of smacks taken. Mages will need to run if they get hate during Oblivion.

6) While it does do some aoe damage attacks, they aren't huge. We had hipotions on all three melees so we could heal ourselves and not waste whm MP.

We ran out of MP with the boss at 10% or so, people started dying but a couple of WS, a big hit from an NPC and good old fashioned Thf meleeing took it down. Icarus wings are nice for the finish here.

Ring. Can I have it?
