Garuda Extreme tips and tricks

Phase 1:  Mark A at NW of field, Mark B at SW of field, then Mark C at SE of field.  Fight Garuda at the north of the field, she summons a whirlwind around the field then jumps, avoid the whirlwind by staying at the center and don't be near the pillars.  Hide behind the pillar closest to you but at the south end as Garuda will appear at the north end of the map and do Minstrel Gust, afterwards the whirlwind will appear again and Satin/Razor plumes will appear to the field.  Kill Satin Plume ASAP, if not it will cast sleep to everyone and slow your dps, then kill Razor plumes and continue dpsing Garuda. If done quick enough, she will summon two sisters Chirada and Suparna.  Thus split the sisters at the north and C, Suparna and Garuda at North of field, Chirada at C.  Kill Chirada then Suparna, then finally dps Garuda while avoid any dmg to the pillars until Garuda jumps again.  The pillars is what allows the party to survive the Mistral Wind move and onto phase 2.

Phase 2:  Garuda will summon Spiney plume and Razor plumes onto the field, dps her while keeping spiney alive and kill Razor plumes asap.  Spiney has a mechanic:  3 stacks of Wind debuff will cause Super Tornado and do 3-4k dmg to everyone.  Prevent that by tank swap between the two tanks in the party.  Also, it does a damaging aoe upon its death but afterwards, creates a protection buff to any wind elemental attacks, ie her Aerial Blast.

Phase 3:  Garuda will appear at the center and summon the sisters again and spiney plume.  Split the sisters again but with Garuda and Suparna at A while Chirada at C.
Keep the swap of spiney in mind while attacking the sisters, but also be wary of the 5 glowing circles on the field as these resonate from time to time where if you're in it while it finish glowing, it will cause dmg and knockback, so go when its not glowing then maneuver to Suparna and kill her asap, thus losing Garuda's protection and dmg buff.  Dps her again until she jumps, then kill Spiney as soon as she does, avoid its dmg aoe then enter its protection to withstand Aerial Blast.  And thus Phase 2 and Phase 3 will repeat from here on out until her death.
