Rai -
The book is a spellbook containing the following spells (You have successfully translated what they are, but may still have trouble preparing them from the book)
Spells - Level 0 - All from Core, Except Divination and Transmutation spells
Level 1 - Disguise Self, Magic Aura, Magic Missile, Obscuring Mist, Chill Touch (DC 16 Spellcraft to prepare)
Level 2 - Darkness, Blur, Invisibility, Spectral Hand, Blindness/Deafness (DC 17 Spellcraft to prepare)
Level 3 - Displacement (DC 18 Spellcraft to prepare)
This book has a Ritual in it. If you prepare 3 or more spells (above level 0) from the book, you gain access to the ritual's benefit for that day.
The Ritual in this book lets you see unhindered in any kind of darkness (even magical) for 3 rounds. Usable in 1 round increments. Swift action to activate.
There is also a recipe for Enhanced Black Smear poison. Craft (Alchemy) DC 18, costs 5 gp in materials, for:
Type poison (injury); Save Fortitude DC 16; Onset immediate; Frequency 1/round for 6 rounds; Effect 1d4 Str damage; Cure 2 saves.
(This is not an instant process and, considering the time given, will likely not be used)
Everything else seems accurate to you, Rai.
And yeah, Sunday is on. 5pm Eastern good for everyone?
None.
