|Final Fantasy X-2 Boss|
- Normal: "A fiend whose impossibly strong shell gives it very high defense. A powerful blow can supposedly shatter the shell, but can that be true?"
Oversoul: "Oversouling has caused its shell to harden considerably. At times like this, all you can really do is smile and keep shelling out damage."
An extremely powerful foe, it will take a while to defeat due to its high HP, Attack, and Defense, along with its constant Auto-Protect. His strongest attack is Megaton Press which does up to 65,000 damage but only hits one person and he only does it every once in a while. Concherer's regular attacks do about 2000-3300 damage. He can drain the party's MP by using Gunk and uses it often.
When Concherer Oversouled Concherer does not use Megaton Press or Gunk, but only regular attacks, Demi, Firaga, Blizzaga, Thundaga, and Flare. These spells can be reflected. Shell is recommended to reduce damage if Reflect is not used. No Break abilities work on the boss.
It is a good idea to bring a large stack of Phoenix Downs and Mega Phoenixes due to its one-hit kills. Using a Light Curtain at the start of the battle helps greatly, as does using Remedies to heal any status effects it can inflict.
One strategy is have a Gunner in critical health with the Cat Nip accessory (which can be won from the previous boss). With the Trigger Happy command, Concherer will be defeated in a few turns. Another girl should revive the Gunner with a Phoenix Down if she dies. A Dark Knight's Black Sky spell is a good alternative, as it hits 10 times.
Another strategy is to use three Berserkers with Luck-enhancing Garment Grids and accessories, plus Reflect Rings or White Magic accessories allowing one character to cast Reflect to block Flare (and to use it to damage the Concherer himself).
