Long-duration Reduce effects?

[AuraSeer]

How would you go about making a character one size category smaller, for a long period of time? Reduce person only works for one minute per level, and I'm looking for something that lasts for hours at least. Ideally, it would be low-level enough to fit in a wand.

On an entirely distinct unrelated subject, isn't it annoying how Eberron Changelings can only disguise themselves as Medium humanoids?

You have a couple of options:

1) Make a new spell.
2) Make a command-word activated magic item.
3) Make a wand using a Persistant Spell version of Reduce (Persistent is a +3 level mod, right?)

Baleful Polymorph him into a Toad.
Cast Reduce Animal.

Edit: Which doesn't really work. What with multiple size reducing effects. Though if you then dispel the Baleful you get to see the rules go 'Boink!'.

Or a new spell or potion (brewed by a high level caster).
