Evrae is a powerful dragon boss in final fantasy 10. At the start of the battle, he will be far away from the airship, causing only long range attacks (Wakka) to hit, as well as magic and Rikku's Mix overdrive. Evrae will only use Poison Breath, Photon Spray and eventually Swooping Scythe (to get in close to the party). At close range it will use petrifying stare to petrify one target, Poison Breath, and Swooping Scythe (which destroys petrified party members). The key to defeating Evrae is to keep everyone out of petrification, and heal between turns. Just chip away at Evrae's HP and eventually (between an hour or several) will fall. When encountered again as a zombiefied enemy, a well placed Phoenix Down will kill it.
