On my DD box I have: 300 - ele weapon 40 - AP Skills 10 - Ditty 32 - Passives 100 - Paagrio pot 50 - Exalted Tiara 50 - 7Signs + Longing 70 - lvl 4 Opal 20 - Level 3 Taurus Agathion 30 - Anakim Charm 702 total. With upgrades I could go higher.

I've just been reading up on element attack. In Salvation all mobs element defense got boosted. You now need 720-780 element attack for max PvE damage. 300 or less and you might as well have no element attack. Going from 300->720/780 seems to give around a 60% damage boost (from them defending 30% extra you you hitting for 30% extra).
