The REAL item level requirement for extremes (becuz dev where drunk)

[Sygmaelle]

Ifrit EX, one of the rare fights in the game where Selene is usefull for something else than dps !

Dat stoneskin combo on top of that magic def buff is rock solid. Learn to your Scholars how to stack fairy's buffs by swappin of when shit get real

Otherwise : it's entirely possible to do it at ilvl requirements. After all Garuda EX is a simple dps check, you just have to save your cooldowns for adds and the encounter is somehow trivial alreay. Even better with ranged since they can profit of requiem when they got to burn them, also go in with a WAR, that -10% debuff is valuable.

It is possible, just use all the tools you got in the game in a proper maneer
