I've tanked it a few times as rdm/nin...For hate i spam bind, sleeps, dispel, silence, blind and cures. I keep hate really well since i got enmity gear...My macro for casting:

input /echo Equipping Enmity Gear
input /equip main "Macuahuitl +1";
input /equip head "Duelist's Chapeau";
input /equip body "Dalmatica";
input /equip neck "Harmonia's Torque";
input /equip ear1 "Eris' Earring";
input /equip ear2 "Merman's Earring";
input /equip hands "Duelist's Gloves";
input /equip ring1 "Mermaid Ring";
input /equip ring2 "Merman's Ring";
input /equip back "Cerberus Mantle";
input /equip legs "Crimson Cuisses";
input /equip feet "Crimson Greaves";
input /equip waist "Warwolf Belt";
pause 1
input /equip sub "Macuahuitl +1";
Needs another eris earring =x

Once it starts casting a ga I switch to resist gear with one of 8 macros that equips an HQ elemental staff + the Belt from the avatar fights + casts barspell. Here's the resist gear...
input /echo Equipping Resist Gear
input /equip head "Duelist's Chapeau";
input /equip body "Dalmatica";
input /equip neck "Jeweled Collar";
input /equip ear1 "Static Earring";
input /equip ear2 "Merman's Earring";
input /equip hands "Duelist's Gloves";
input /equip ring1 "Merman's Ring";
input /equip back "Lamia Mantle +1";
input /equip legs "Crimson Cuisses";
input /equip feet "Crimson Greaves";
pause 1
input /equip ring2 "Merman's Ring";

Only SS i could find of damage I've taken...This was when I first tried it out and RMT had popped jol so this is with 2 people getting hit by agas. I normally take around the same damage with shell5 though. Ocasionally you'll completely resist its agas and they won't break stoneskin, and fairly often you resist his enfeebles.
