|Taking a page out of Lewyn's book, this build seeks to shred targets with AoE procs from the second round of combat onwards. Once Ishtar is in Juicy Wave+'s range and has entered into combat at least once, she basically unleashes 3 devastating, consecutive strikes onto the opponent.
In the first combat, Flashing Blade 4 should ideally proc, charging Blazing Wind from 4 to 2 on the first hit, and 2 to fully charged on the second; in every subsequent combat, Blazing Wind procs before combat, and its charge goes from 4 to at most 2 if Flashing Blade 4 procs (and Guard 3 does not), allowing Special Spiral 3 to bring the charge back from 2 to fully charged once more.
Unlike Lewyn, Ishtar needs to lose HP to proc the weapon's Desperation 3 effect, so Fury 4 is preferred to more safely get into the low HP range. However, if Ishtar is running Reciprocal Aid, then she can forgo Fury 4 for the stronger but more dangerous Life and Death 3. The reason why these skills are used instead of, for example, Swift Sparrow 3 is that AoE specials take into account only visible Atk, not invisible combat buffs.
