Elephantine Growth [Reserve] (Seto)
You are able to swell to titanic sizes, growing large to smite your enemies.
Prerequisites: Ability to cast 3rd level or higher transmutation spells.
Benefit: As long as you have a 3rd level or higher transmutation spell available to cast you may cause yourself to grow 1 size category, to a maximum of huge, until the start of your next turn as a swift action. If you have a 6th level or higher transmutation spell available you grow 2 size categories, to a maximum of huge, instead and if you have a 9th level transmutation available you grow 3 size categories, to a maximum of huge. Your reach increases if appropriate, and you gain +2 to Str, -2 Dex, and +2 natural armor for each size category you actually grew as your flesh becomes grey and leathery like an elephants. Once you have used this ability you must wait 1d4 rounds before using it again.

As a secondary benefit of this feat you gain a +1 competence bonus to caster level with transmutation spells.
