this seems to be an interesting interpretation, can you expand on what your saying?

Question: Can Sarishan Sorcerer-Priests use Wands?
Answer: Yes as per the description (FiM v. I pg. 343)
Sarishan Sorcerer-Priests are trained in Eldritch magical
techniques, as such they can use wands. Also due to their
unique nature, they can use magical Holy Symbols attuned
to their god as well.

Wands
At the end of the first paragraph change the last sentence
to the following:
Not all practitioners of magic make use of wands;
only those who practice elder, eldritch (including Sarishan
Sorcerer-Priests) or primal magic make use of such items.

In saying that the Sorcerer-Priests of Sarish use Eldritch (listed as a specific Magical Source), it completely runs against saying that Sorcerer-Priest of Sarish is its own source. As such, all SPS's MUST take Arcane Spell Casting: Eldritch for their powers and not this unique system they have. Knowing the story, the universe, and Sarishans, I understand what the Errata is TRYING to say, but to a casual reader the use of key words is confusing. As such, you should say that "As the traditions of the Sorcerer-Priest of Sarish are rooted in Eldritch Magic, they are also able to use Wands".

Basically, you cannot say that their magic is eldritch because that word means something very specific in the game which does NOT refer to them, which leads to confusion.

so what you are saying is that this should be changed, let me go ahead and actually propose a wording change then (changes in purple to reflect the beneficence of sarish):

PG 7 of the FAQ under Magic Items:


and then again on PG 14 in the Errata

For all purposes the source, Sorcerer-Priests of Sarish, counts as either Eldritch or Divine. Thus Arcane Spell Casting: Sorcerer-Priest of Sarish can be substituted for either Arcane Spell Casting: Eldritch or the Divine Spell Casting talent to meet the requirements for use of any magical item or meeting the requirements of any Talent, Path, Background, Fighting Style, or anything else we make up in the future.
