Final Fantasy X Walkthrough Part 93 Yunalesca

Part 93 - Battling Yunalesca part 1 of 2.

Due to events before battle and YT time limit I was not able to put it in 1 video.

Anyway, I'll cover the start and preparation here and everything else in the next video.

First off, she has 3 phases. The first one is weak, but still annoying as heck because it can be hard to even build up here.
Her normal attack dispels all your buff(does not affect Reflect!) so your Haste buffs will be gone if she hits you with that.
If you attack her, she will counter depending on what you hit her with. Spells she counters with silence and physical with Blind.

Only way to deal with this really is to have anti-proof on armors or simply the easy way - Cast Reflect.
The bad thing with Reflect is that if she dispels your haste, you won't be able to cast it again since Reflect isn't affected by her dispel.
I wouldn't worry to much about healing as you'll be affected by Zombie frequently in phase 2 and on and before hand you can still cast Al'bhed potion / Mega potion that isn't affected by Reflect.

Her second form uses Hellbiter which deals 200-300 damage to all and turns you Zombie. You could cure it to heal, but make sure you stay Zombie before you finish phase 2 or you will die.

Anyway, her second form starts casting Cura/Regen etc to kill you in Zombie mode. You can avoid this completely by still having reflect up. Most things she has will be cut away, but you won't be able to heal much at all in the fight and she'll heal herself.
Cura is not too bad, but Regen HAS to be dispelled if you reflected them!

I wouldn't worry about losing to much health, just switch characters sometimes and be ready for phoenix down. She doesn't have a lot of ways to finish you off.
