Spells

To make sure spells are balanced I tried just to alter existing ones for flavor. If that is the case I mention the base spell in parantheses after the description.
Also I try to add reason for the spell level in cases where there is no base spell. This should keep this list more in line to the spells in game, than those you find all too often on fan-sites (or some published D20 or even DnD books)

Arousal

Enchantment
LevelSor/Wiz 2

Like reduce Person, but the target doesn't need to be humanoid and it gets reduced by 1+Level/5 size categories. (for example a level 10 character can reduce the target by three size categories)
The target gets a +2 size bonus to dexterity, a -2 size penalty to strength (to a minimum of 1) per size category shrunken. For AC and attack bonus refer to the PHG (page 134)
Shrinking by one size category divides the size by two and the weight by 8. (Just apply those reductions several times if shrunken more than one category at once)

The material component is a bit of hair.

Rip Pocketplane

Durationinstantenous
Saving throwNone
Spell Resistance No

You can rip a part out of the plane you are on, to create a pocketplane.
For each XP Point you spent, you can increase the spell radius by 1' (starting at 1' radius with the first XP you spend). You don't have to put everything in that spell radius into the new pocketplane. (i.E. if you only want to make a certain room in your mansion a plane of it's own)
The new pocketplane has all the traits of the plane it was ripped out. The accesibility to the parent plane will be at the level where you can just walk from one plane to the other. (In other words, there won't be any visible difference, until someone use planecrafting to make differences to the pocketplane)
