Due farming I already got 5 green Pan's (don't need them) and 2 green's Iris.
Farming time about 6h gives on 68th around 500 Essences (Wind or Water) + 2-4 Pan/Iris Seal.
Exchange 60x Essence of Wind/Water to 1 Pan/Iris Seal.
The drop rate for green one is about 10% - One green Pan/Iris from 10 Pan/Iris Seal.
7h farming gives You good chance to get green Sylph.
Blue Sylphs: I would expect 1% for blue Pan/Iris...
P.S.: Farming for mage it's not a problem - suntoria + 2x bolts... next one... no HP loose...
umm we need more data to come on any fixed ratio..
i might have farmed 300 wind essence got 2 green while i had just farmed 200
took me a while for iris might hv farmed 600 essence to get 1 green iris..
and i knw smone who got blue by farming pretty much same amount..so we can say its still more towards luck..
P.S- people shouldlevel up..get stronger...then they too wont hv to stick to MAGE can just sunt type of thinking to save ur hp....those who r higher level and stronger and not just level camping they r killing in 3 shot as rest dmg is done by troop alone...
i myself 3 shot them...and i pretty much afk it...
