I was looking into the new flasks (i.e. flask of restless dreams and everlasting nightmares) and noted it shares the same extensive quest line as other epic craftable items. Does crafting 1 flask use up the inert mantle of nightmares (meaning I have to kill the amalgam again to get another one)? Even if the inert mantle is reusable, requiring 10 nightmare seeds for each flask seems like a waste of resources.
It would be great to have the flasks be reusable. Increase the reagents to be equal to that of the craftable epic equipments, increase the cooldown, and/or have it persist or not persist through death. As it stands, the only way I can seeds is in ST which requires a raid or a class that can solo the whelps. Also the other epic craftables only need to be crafted once and apply a permanent buff to the character.
