Damage

Damage is a stat belonging to most but not all minions and determines how much health a champion loses when that minion attacks them. Damage can be increased via the Spellbook, the Reaper and Relics. In game purchases also increase certain stats like damage.

Boosts
All boosts are additive. This means they total up to a single factor that your damage is then multiplied by, such as: Damage = BaseAttack*(1+F) where F is the sum of the boosts. This means that increasing F by 100% will not necessarily double the damage. For example, with an increase of 30%, F goes up by 0.30, but if the total increase was already 170%, F was already 1.7, hence the total damage is now multiplied by 3.0 instead of 2.7, which is only an increase of about 11%.

Champion Health
Note: Although the Thief is not actually a champion, due to it being a daily spawn with health it has been included here
