The Boss in the Holla Spire casts plague. Is there any item that can cure plague, because when you are a group of Whm, Blm, Pld, Drg, Sam, and (honestly I forget what our 6th was). We were screwed when he hit us with a strong plague. It drains both TP, and MP so you are basically dying a very slow death with that on.
Also it does not take an alliance to get to the Spire. In fact when we did it with an alliance it was harder because things were very unorganized. With a party here is how we beat each of the Memory Receptors.
First we cast bio on the thing, of course it used its Empty Seed move. Then 1 of us would pull a stray build TP on it. First one with 100% TP, would go to the MR use it's best available WS, usually this caused a stray or 2 to link, we killed the strays, every time 1 person got 100% TP we would use that on the MR. I would use both my WS and Jump for a little added hit before his AoE knocked me back to the group.
We repeated this process of 1 person running in and using WS until it was dead. The mages healed, never nuked. It was a slow battle but the damage done was steady and consistant.
Also with a little stealth you can make it through the 4th floor to the spire with little to no battles at all. you just need to be patient and organized. It is pretty much a 1 way winding road to the spire.
Of course we died from the NM at the spire, due to his AoE plague move. But, we plan on getting some items(we went in with echo drops, holy water, hi-potions, because we were expecting him to use silence AoE and Curse, but he did neither of these). We got his health down to about half before he killed off the last member of our party.
