Other Uses for Alternate Source Spell

[KarinsDad]

I will be playing in a Pathfinder game where the DM might allow my PC to use the Alternate Source Spell feat in order to qualify early for Mystic Theurge. I wanted to be higher level as a Wizard than a Cleric, hence, the reason to not take Precocious Spellcaster.

Alternate Source Spell [Metamagic]
You can prepare any of your spells as either divine or arcane.
Prerequisite: Ability to cast both divine and arcane spells.
Benefit: You can choose to prepare any of your divine spells as arcane spells or any of your arcane spells as divine spells. An alternative-sourced spell uses up a spell slot from the class that normally grants the spell. such a spell is prepared normally. An alternative-sourced spell is cast as if your caster level were 1 level lower. For example, a 1st level cleric/6th level wizard casts a divine fireball as a 5th level wizard.

I haven't played 3.5 in nearly two years, so I cannot remember a lot of it.

Can anyone think of a use for this feat other than to qualify? Are there foes that take more damage from divine sources than arcane ones, or vice versa? What would be a good reason to create a Divine Fireball or an Arcane Magic Stone?

Thanks.

The simplest answer is - you can double the spells per day of one of your classes. If you don't give a whit about your Divine spells, you can prepare them ALL as Wizard, or vice versa. More spells = more win.

I don't understand this.

Say that a PC has 4 spells total, 2 divine and 2 arcane (for simplification) and that PC prepares:

2 Divine Cure Light Wounds
2 Arcane Magic Missiles

The next day, he decides to make them all Arcane.

2 Arcane Cure Light Wounds
2 Arcane Magic Missiles

He still has 4 spells total and he still has 2 Cure Light Wounds and 2 Magic Missiles. Zero gain. The only difference is that the Cure Light Wound spells are now Arcane instead of Divine.

He cannot prepare 4 Arcane Magic Missile spells with the feat.

Arcane Spell Failure doesn't apply to Divine Spells.

Found this thread while searching. It's a bit old, but still relevant since I'm planning on doing much the same as the OP, but with a sorcerer rather than wizard. My question, can a spontaneous caster benefit equally from this feat?
