Vial of Viscous Mana

[Caleban]

Hey,

Looking to get my hands on a stack of vials of viscous mana. I have never seen these for sale in EC nor have I ever seen them pop up on the EQauctions tracker. Having researched them, I see they are the result of a lvl 12 enc spell which requires a couple of agents. Is the spell one that is commonly bought by enchanters? Would I stand a chance of landing a few vials if I stood around EC with the required agents and advertised in /auction? Just want to figure out whether my only option is levelling an enc to 12 to get my hands on some of these.

Thanks!
