You are lucky there is very little holy priest spells within the tome, the closest Isaik get its discipline and that branches into a whole chapter bent on using light and void to see the timeways of the future. Funnily enough the amount of holy specific spells wrote by Zalak himself nears about three or four… The rest was from a human priest attempting to defile a copy of a tome by writing holy scriptures across its pages… The tomes do what they do best and even that was chronicled…
There are some Druid spells in the tome, consider it the almanac of magic. But just because the spell exists does not mean the reader can harness the power to use them. Basically a gnome reading a Druid spell is still likely not to be able to cast it.
As Yumara knows I gave up on that long ago, no threads of the future leads to a timeline where I control the witch… I may be a powerful creature but I do not test fate… not anymore…
Complicated answer, Salkeen saw Jericha and felt a will to make her his minion… Isaik sees what Salkeen saw and thought it was a good idea further encouraging something that would already happen. Salkeen would have contracted Jericha without Isaik’s involvement, Isaik just encouraged the action.
A stronger artifact than that dagger she ate…
This will be a challenge as the two are so closely alike each other… I guess the biggest difference is Isaik aims for something higher and sees Ebony as wasteful… We will see if he can convince either way…
