You are fast sir!
Edit: I also forgot to ask, you mentioned in an earlier post that boss morphs were being put back in. Is this in the latest build now?
No, not yet; I need to go through all the bosses and decide what to put on them.
How do we cure or prevent zombie status?
Im at the final disc one boss fight and that zombie status is screwing me over.
Zombie can't be cured or prevented; the character afflicted with the status should be first priority for MBarrier and Poison/Dual-Drain should be healed off the character with Antidotes or Esuna ASAP. You can block Degen and Rigor Lock if you have a Lv.2 Elemental Materia by combining it with a non-elemental Magic Materia like Seal, or by accessories that block the statuses attached to them (Dual, and Slow/Paralysis; Jem Ring is a good shout). You can also take a risk and use Sleep on Jenova here, but there's a 25% chance of it waking up after each action and counter-attacking with a unique attack so only do this as a last resort.
You'll want to be aggressive and try to get the fight wrapped up quickly before things get out of hand. Try and inflict Slow on her (Shiva can do this 100%) at the start of the fight, and get MBarrier up to help block incoming damage on your Zombied character. Element-wise, Holy and Earth should work. You can get Holy onto a weapon by combining Elemental with Restore Materia if you don't have more than 1 Earth Materia (Titan can also be used), and she has relatively low Magic Defence compared to other bosses. I'd try avoiding the use of Sadness here as well because you'll want to be throwing out Limit Breaks for extra damage. Your group can be in the front row as well with no risk, as none of her attacks are physical.
