Damage modifier

Damage modifiers refer to the buffs or debuffs applied to a unit that causes it to deal or receive increased or decreased damage. These are percentage values. They don't add extra flat damage but modify all damage normally done. These buffs or debuffs are only received by champion abilities, neutral buffs, on-hit effects from items and masteries.

Damage dealt modifier
These are buffs that allow the champion that has them to deal increased or decreased magic or physical damage from basic attacks, abilities, and item actives. The raw value from the attack or ability is increased or decreased by the modifier and then applied to the target.

All damage dealt modifiers stack multiplicatively. Since multiplication is, the order is irrelevant. So if uses an autoattack on a CC'd champion just after using a maxed  on it, while affected by, his autoattack's damage will be modified by 107.525% (110%115%85%).

Flat Damage Reduction
Several champions have abilities that reduce damage by a flat amount.Some flat damage reductions are factored in after armor or magic resistance. This makes it significantly better the more resistances you have. In addition, periodic damage effects will have each tick of damage reduced. For example, ticks 8 times, so 1 flat damage reduction would reduce its total damage by 8.

Flat damage reduction does not work against true damage.

Items
