NEVER EVER EVER EVER Overloard while fighting Ob.
I've killed it a grand total of ten times now (Yay Coiler on the 10th kill). Our 11th fight I deactivated and reactivated my Spiritreaver to refill his MP gauge and we went into combat.
At about Ob's 50% mark I accidently Overloaded. He then went BATSHIT CRAZY and obliterated everyone. It was absolutely spectacular. He was swinging at borderline Hundred Fists speed and was throwing ultra high damage TP attacks about as fast as one possibly could.
Not even the melee versions of Ob become that deadly at low health. And he was in his BLM mode whooping melee ass.
Needless to say we wiped.
Also, I hadn't heard anyone specify, but Ob only mimics the frame of your automaton, it completely disregards the head you're using. Oh yeah, and make sure your NIN tank's shadows are up before you pop it... I caught my tank off guard and he voked before shadows were up and Slapstick was insta-kill. He might also be affected by a PUP's maneuvers but nothing I really noticed. I used Sharpshot frame + Valor head to force him into rng mode so there were no -GAs and no Magic Mortars. Much more managable although Armor Piercer and Daze can be brutal if they catch you at low hp and no shadows. Hate gets pretty wacky in that fight because of how much damage he can do at once and all the cures being tossed around and the nukes... my automaton pulled hate once or twice at about 50% ish as well with Armor Piercer. I would never recommend fighting Ob without a PUP. With one, I think Ob is the easiest option for Cerberus path.
Ob does -not- mimic the frame. He mimics based on the maneuvers you use. I noticed this when our tank got hit hard and I popped Light Maneuver to trigger Flash. Ob immediately responded by turning into Valoredge. Figuring that Valor was weaker to getting nuked, I put up an Ice Maneuver---he turned back into his BLM form.
I feel safe in assuming that Wind would cause Sharpshot to happen. The reason we think that frame=copy is because these are simply the natural selections you'd make with your respective frames. But if you engage Ob and don't put any Maneuvers up at all then nothing happens. Soon as you put up Ice, though, bam. Instant enemy BLM.
