Also mention in the stats section that the health regeneration is between 10 and 25, the mana regeneration is between 11 and 23.

Additionally, other points that worth to mention such as the value shown of attack speed represents the number of attacks per second and that is capped at 2.5 or that the percentual damage should be seen by the author as "HP Removal" rather than a mere scaling damage are possibly useful tip to tell.
