I've been playing a blue mage for about 2 weeks on b2 and attacking whites and I used sirene/sylph/mind ripper/water/ice/sal i used this at around rank 500-1200 most whites at that rank are big gate users and you'll find alot with angels in second stack and sylphs will take care of angels any day and I only kept one cast of water and ice so that I could keep a positive mp income i would keep 30 of each elemental 1000 mind rippers and 2500 sal and i would power up with sirene and sylph to attack 13-15k sirene and 18k sylph when attacking and about 8k of each when defending
now that I have made it into the higher ranks I'm not sure what to do but so I made unicorns and archangel my first and second stack and got an extra cast of each elemental and for getting land I'm not sure yet I think i'll try 30k sirenes on carpets and see what i can do with that its an old Rava trick
==================================================================================
try this stack..
Arch
uni
lich
mindripper
and fodder...
that's what 50 rank mages are using for blue.. to difficult to break..
