Proficiencies: Spellwarped creatures don't gain any new proficiencies.
Spellwarped Body: Unlike with other monster classes, the traits of the original race are retained. The Spellwarped Creature then gains aberration traits (basically darkvision 60 foot) and is now an aberration, with the augmented subtype if necessary.
It also gains a natural armor bonus of +1. If it already had a natural armor bonus it increases by an extra +1.
Spell Resistance: The Spellwarped creature gains Spell Resistance equal to 15+HD. It may rise or lower it at any time as a free action. If it already had SR increase it by 4 instead.
Experiment: The spellwarped creature gains +1 to the ability score of his choice.
Experimental Power:Spellwarped creatures were engineered to be strengthened by magic. Whenever a spell or SLA fails to bypass it's spell resistance the Spellwarped creature gains the following bonus of his choice for 1 minute, where Y is the level of the spell or SLA stoped by the SR
Power: +Y enhancement bonus to the ability score of his choice.
Life: +Y x 5 temporary hit points.
Speed: all move speeds increased by Y x 5 foot.
Resistance: The spellwarped creature gains resistance Y x 2 to the energy type of his choice.
Bonus of the same kind don't stack.
Whenever a spell or SLA is absorbed the body of the spellwarped creature is temporally warped in some hideous way acording to the bonus gained, like muscles stretching when a strength enhancement is chosen.
Advanced experiment: the spellwarped creature gains an extra +1 to each of two ability scores of it's choice.
Comments
The first level of the spellwarped creature grants powerful SR and a minor natural armor bonus together with a small ability score increase of his choice to make it less dul. The second grants two extra ability scores and the experimental power ability to absorb spells.
Some showed problems with the original ability being too strong with spellcaster allies using low CL stuff, so I made the bonus dependent on the spell level and last very little time. Sure the spellwarped creature can gain +9 to all ability scores, but that now demands six valuable 9th level spells, and they don't stack with enhancement bonus and will only last 1 minute. You're better off using those spell slots for actual buffs.
Plus you don't gain any other ability for the second level.
Kudos to Frog Dragon by contributing the base template for this.
