I'm kind of embarrassed to ask this given that I have a level 300 enchanter. Anyway.
I need to get two mongoose enchants on my new weapons. On my server the mats run around 600g. If I am supplying the mats, can the entire enchant be done through the trade window, or do i need to actually give the mats to the enchanter first (giving them an opportunity to "thanks for the mats" /ignore.)
