Regarding duals A grade in 2.0

[Arcanum]

let me get this straight: what will we need to craft A duals in 2.0?

i'm asking because after searching infos for an hour, i've found nothing at all, therefore i'm still wandering in the dark.

i did find a list on the the KR wiki thou: http://lineage2classic.power.plaync.com/wiki/A급+이도류

as you can see, the only available duals A grade in 2.0 are kesha*kesha and kesha*damascus, however there's no method/materials needed to create them written down anywhere.

any infos from the admins will be much appreciated, especially because i'd rather not waste all my money on something that doesn't exist/cannot be created in 2.0( dama*dama or dama*tallum, for example ).
