Yunalesca is a storyline boss from Final Fantasy X fought in Zanarkand Dome. The battle with Yunalesca is fought in three stages, with her becoming more demonic with each change. Her third form resembles the sprite of Goddess from Final Fantasy VI.
The Sun Crest can be found after defeating Yunalesca, revealed by going down the end set of stairs. In the PAL, International and HD Remaster versions, if the player does not obtain it upon her defeat, the next opportunity they have to obtain it is after defeating Dark Bahamut.
Yunalesca has three forms, each of which has a separate HP pool. Whenever a form is defeated Yunalesca will immediately transform into her next form.
Yunalesca's first form will counter all physical attacks with Blind, magic spells with Silence and Special commands with Sleep. On her turn Yunalesca will alternate between a weak physical attack which removes positive status effects except Reflect, and Absorb, which inflicts damage equal half of the affected character's maximum HP and heals Yunalesca by the same amount.
Yunalesca will start the second round by using Hellbiter, which puts all characters in Zombie status, and then will cast healing spells such as Regen and Cura on the party. She will often counter-attack any hits against her with a weak physical attack with the same properties as in her first form.
Yunalesca will begin the third round with Mega Death, which kills all party members who are not afflicted with Zombie. Yunalesca retains Hellbiter, Regen and her physical counter-attack from her previous form, however she now has access to Curaga which she will use against a party member and Mind Blast which attempts to inflict Curse and Confuse on all party members.
When an aeon is used against Yunalesca in any form, she will cast Absorb on them on every turn.
The fastest option assuming one doesn't care about everyone getting AP is to steal four Fire Gems from Flame Flans in the Calm Lands and ensure Rikku can mix Trio of 9999 (Quartet could work, but it would need to land on someone who has the ability Use). When facing Yunalesca, Rikku must mix Trio of 9999 and throw four Fire Gems for a quick win.
Before the battle, it is useful to have Yuna and Rikku reach Overdrive, along with any aeons. It is beneficial to customize the ability Auto-Med (or find an item) on either Rikku, Wakka, or Auron. When the battle begins, the trio should be in the starting line-up and steal a Stamina Tablet from Yunalesca. It can be used in mix with a Potion and to get Mega Vitality, which will double everyone's hit points. Yunalesca's greatest weakness is her lack of strong physical attacks, and Wakka and Auron's 8,000-10,000 hit points functions nicely for offensive purposes.
Yuna is handy for Reflect and Esuna. When the second phase starts, the party should continue the same strategy, mixing in Overdrives, although Yuna is needed to Dispel any Regen that might land. Whoever is the Auto-Med can function as a curer and use Holy Waters to cure the Zombie. A good follow up is to have Yuna use Curaga afterwards. However, the party must be sure to always keep at least one Zombified player on the field in case of Mega Death and the rest of the battle should pass easily.
An alternate, and perhaps simpler, strategy is to capture one of every type of fiend that exists in the Calm Lands for the Monster Arena owner and he will reward the party with 60 Farplane Winds, which can be customized into the Deathproof ability. This is especially useful for Yuna to immunize her to Mega Death even without the Zombie status so she can revive and heal the other characters. It is also possible to use Auto-Life to survive Mega Death by either casting the spell or by using Rikku's Hyper Mighty G.
If Yuna has learned Holy, it is a good time to use it.
