Are there any guides on imbuing items? There doesn't seem to be much about it in the game and there's a very limited number of FAQs for that game right now.

And finally, where to get those vitae
Wind Runes = Parnus Way (1 screen south of Witch Village)
Fire Runes = Northring River (1 screen south of Witch Village)
Nature Runes = Mountains east of Lethe Forest (1 screen east of Witch Village)
Water Runes = Ship battle (Just south of capital city)
Thunder/Dragon Runes = Lost Desert (Near the last area)
Light/Darkness Runes = Snowfield (Near the last town)
Neutral Runes = Heavily Forested Path (Right witch village)
Theres a Microsoft Excel file out there that has the translation from Viate name to the traslated name (but you still have to pay the witch sisters).
Those are all just rare items that you can make from items, but you could always take a normal item, add a Dragon Rune to it and a HP+30 to it to give them those effects.
