The Special at the bottom of the Initiate of Mystra refers to anyspell & greater anyspell. "With this feat, you can cast them as reguler cleric spells, not just domain spells."
That should clear it up nicely. Keep in mind that these spells must be prepared as a Wizard prepares them, IOW the cleric has to have access to a scroll or spellbook, they don't just pray for them.
This means an Initiate of Mystra may fill a regular 3rd level slot with any arcane spell they have access to up to 2nd level and later they may fill a 6th lvl slot with any arcane spell up to 5th lvl. This seems a bit over the top unfortunately, balance-wise. To fix this from getting out of control it would've been better if the Initiate were allowed to fill their domain spell as normal with Anyspell and then 1 additional regular slot, but not potentially all of them. Imagine a Cleric memorizing several Firebrands in their 6th lvl slots and Scorchign Rays in their 3rd lvl slots, Yikes. That's definately stepping on the arcane caster territory there.
Except that's not what it means.
Also look at Initiate of Selune or Initiate of Gond.
They also have the text "The insertspell spell also appears on x domain list. With this feat, you can cast it as a regular cleric, not just a domain spell."
Given that Fantastic Machine, Moon Blade, and Moon Path also are given the exact same wording.
All that text says is that you can cast the Anyspell or Anyspell, Greater spells as regular cleric spells. It doesn't change any of the text of those spells, the effects of the Anyspell still only occur in the domain spell-slot. Now if the text of Anyspell said "replaces the spellslot that was occupied by Anyspell" it would work as written.
The intent may well to work in that manner, doesn't mean that's what the RAW supports.
It does still hold some benefit, however, with the prepared Wizard spell only occupying the appropiate domain slot. You can change the prepared spell throughout the day if you have the time, adding a level of versatility. Admittantly, that's a really minor benefit and really necessitates having a "spell already prepared" in a given domain slot and wanting to change that spell.
Now, the fun part is that I'm not sure if casting the spell (normally, assuming not an Initiate of Mystra) 'refreshes' the 3rd level domain slot. Or does the cleric have to wait for a day to get that spell-slot back in order to cast it?
If it refreshes, there's an added benefit of being able to effectively have multiple wizard spells cast in a given day, you just have to spend 15 minutes refreshing the spell-slot.
