Level VIII Scroll Creation
Players may obtain quills, inks, and glyphs from the new highest tier treasure profiles which may be used to craft spells. Quills may be combined with the Mana Scarabs (which are also the casting scarab for level 8 spells) in order to craft infused quills. Infused quills may be crafted with inks to create a combination of the two. This combination may then be crafted with a glyph to create a level 8 scroll.
All components may also be traded or sold to a vendor, and the scrolls may likewise be traded or sold to a vendor. If crafting something you expected to work fails, very likely the spell simply does not exist for level 8. You will not lose components upon failed crafting, and there is no skill associated with level 8 spell crafting, so feel free to experiment safely with the various components and see what you may accomplish!
