Primal Form: Colossus

You transform into a Gargantuan avatar of primal power, growing to enormous size while retaining your mental faculties and spellcasting ability. Your equipment grows with you or merges into your new form. You gain massive physical prowess and the ability to affect the environment on a grand scale.

While transformed, you count as your original type and the form's type for effects that care about type. You can cast spells; verbal/somatic may alter with the form; components must be worn/merged or replaced by a focus. You can't end your turn inside a creature or object. Your natural attacks count as magical for overcoming resistances. The DN provides specific statistics for the colossal form.
