You now have the ability to take on a series of immensely powerful transformed states of your own design, with the first one giving a 10x boost to all your powers and physical stats, and the others after that offering a 10x boost to the previous form. These transformations could take a myriad of themes and appearances that follow them, maybe you want to look more animalistic or more regal, have a more monstrous theme etc, you can choose and design each form provided it follows your transformation's theme.
Note, that each form drains stamina and the stronger the form is the more stamina it drains and if not careful, could kill you, this can be mitigated through training.
You start with your first form and can unlock more in the future through training or a sudden boost of extreme emotion such as rage
