Hello and welcome!!

We're going to need to look at your character a little, in terms of turning into a lion.

The strength, agility and endurance need to be discussed a little. Lions are roughly 20x as strong as a human being (male lions) and many times as agile. For now what I suggest is you rate it in terms of a 'times' that you could increase with levels, though I understand it will not be as strong as a real lion. For each of these stats a 2x or 3x the average human should work.

Happy to be open to discussion. Your earth bending is fine more or less, just needs clarity - can you use it for combat? And is she able to control plants as well.
