The strength of a character at this level is at max that of an olympic athlete and only if they have sufficient background granting such physical prowness. Speed is capped at around 26mph and strength at about 300lbs without breaking a sweat.
Level 3|| If Level 1 is the base human level, and Level 2 is the natural prodigy level, Level 3 incorporates what Hollywood writers think real human beings are capable of. In short, Level 3 is supernatural, but still within the realm of suspension of disbelief. You can now throw fireballs and other simple spells or powers though expect to be exhausted if used frequently. Telekinesis is available to the point that it can stop a bullet, though it would also be incredibly taxing, and characters are able to lift objects several times their weight.

Level 8 || Your powers can cut down small armies, and shield you from the effects of nuclear weapons. You are no longer merely limited to visiting other worlds and epochs from afar, but may now visit them personally. Powers are of a scale capable of affecting entire planets, or of affecting locations across solar systems and dimensions.
Level 9 || That your powers rank less then omnipotent and have finite energy requirements are essentially your only restrictions at this point. Level nine powers can affect entire galaxies, and entire star systems across multiple dimensions.
