Polymorphic Titan

You can transform into utterly enormous creatures.

Prerequisites: 17th level, you know the polymorph spell as a 6th-level spell, and you have at least one Huge predetermined polymorph form.

Benefit: When you cast polymorph on yourself as a 6th-level spell to transform into a Huge predetermined form, you can spend 1 Edge to transform into a Gargantuan version of that form instead. The Gargantuan form grants a +4 enhancement bonus to Strength-based ability checks and skill checks. Alternatively, you can spend 2 Edge to instead transform into a Colossal version of that form with a space of 30 feet, granting you a +5 enhancement bonus to Strength-based ability checks and skill checks.
