Oracle + Spiritual Weapon spell: Wis or Cha?

[Bellona]

The Oracle class (APG) draws its spells known from the Cleric's class spell list, but uses Charisma as its spellcasting stat (instead of Wisdom as the Cleric does).

The L 2 Cleric spell Spiritual Weapon specifically mentions using the caster's Wisdom modifier when calculating the spell's attack modifier. Would it not be reasonable (or even RAI) for an Oracle using Spiritual Weapon to base the spell's attack on Charisma instead of Wisdom?

The same question could just as easily be posed for Spiritual Ally, a Cleric L 4 spell in the APG which could also be chosen by an Oracle.

I do hope it gets erratta'ed to "Casters appropriate casting stat" but i havent seen any ruling on it mayhap someone else has?

[Ravingdork]

It sounds reasonable to me.

[Kvantum]

Mage's Sword uses Int or Cha as appropriate to the caster to determine its attack bonus, so I can't see any possible justification for why Cleric/Oracle spells shouldn't work exactly the same way.

There are a number of spells that should probably use generic "casting stat" wording instead of specifying a particular attribute (e.g. Telekinesis).

Has Spiritual Weapon been addressed anywhere by the Paiso gurus for Oracles using CHA as the stat instead of WIS?

Apologies if it has, but I have not seen any official response anywhere yet.

Thanks!
