The CHEAPEST way to get the Ink you need...
Go to Kainang Center
Go to the [Materials] guy across from the Dye Trader
Take with you:
>75 Glittering Dust
>60 Plant Fibers
>1050 gold
Have him craft you 15 Tempered Glass Vials with the Dust and 300 gold
Then have him craft you your Ink with the Fibers, Vials and 750 gold
It's just that simple :-)
