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!

Creating spells.
Add the quill to the mana scarab
The mana scarab infuses the quill with its magical power.
Add the infused quill to the ink.
You dip the quill into the magical ink, further empowering it.
Add the enchanted quill to the glyph.
You trace the rune with your enchanted quill and the pattern of the spell forms before you as a scroll.
This produces a tradable scroll which you can then learn as normal. Level 8 spells last for 89minutes, or up to double that with augmentations. Success rate with skill buffed to 435 was about 33%
