Words and Runes to not vendor

[Videri]

In my opinion, here are the most valuable pages and the spells they make

Enc
Tasarin’s Grimoire p 26 left and right for Mesmerization (Target-based AE mez)
Tasarin’s Grimoire p 312 left and right for Color Shift (PBAE stun; combos nicely with other PBAE stuns)
Velishoul’s Tome p 109 and faded pages for Feedback (enchanters’ only targetable damage shield)
Salil’s Writ p 288 and faded pages for Mind Wipe (not all of them will want it, but memblur spells can be very powerful)
Nilitim’s Grimoire p 35 and 36 for Pillage Enchantment, 4-slot dispel
Nilitim’s Grimoire p 115 and 116 for Color Skew, another PBAE stun
Nilitim’s Grimoire p 300 and 301 for Shiftless Deeds, level 44 slow
Nilitim’s Grimoire p 378 and 379 for Allure, a charm spell
Nilitim’s Grimoire p 415 and 416 for Blanket of Forgetfulness, target-based AE memblur

Perhaps players more experienced as enchanters on P99 can comment.

Pethaps someone else will follow suit for other classes. I might do it myself later, but I don’t feel like more of this right now.
