Several Skills and Traits modify a champion's Stats. Buffs are positive boosts that
are applied to ally champions and Hexes are penalties or damaging effects that affects
enemies. There are many different modifications that are applied with Buffs and
Hexes, and they stack in different ways. Buffs and Hexes from the same source never
stack. Each Buff or Hex has duration in seconds. Effects from the Buff or Hex will
expire after the duration has ended.
Speed Buffs/Hexes - Skills that affect a champion's Movement
Speed will either add or subtract a percentage of their Base Movement Speed. For
example, a champion with a Movement Speed of 210 that receives a +10% Movement Speed
buff will have a Movement Speed of 231. Additional buffs to Movement Speed will
be modified by the modified Movement Speed of 231. Movement Speed cannot be raised
above 350 and cannot drop below 60.
Physical and Elemental Resist Buffs/Hexes - Skills that
modify a champion's Physical or Elemental Resist will add a percentage to their
current Resist rating. For example, a champion with a Physical Resist of 15% that
receives a +10% Physical Resist buff will have a total Physical Resist of 25%. Physical
Resist cannot be raised above 80% and cannot drop below -50%. Elemental Resist cannot
be raised above 50% and cannot be drop below -50%.
Attack Damage Buffs/Hexes - Skills that modify a champion's
Attack damage will increase the champion's Base Attack Damage by a percentage. For
example, a champion with an Attack Damage of 150 that recieves a +10% Attack Damage
will have 165 Attack Damage. All further bonuses or penalties are modified from
their current Attack Damage value. Attack Damage buffs and hexes does not affect
a champion's Skill damage.
Attack Speed Buffs/Hexes - Skills that modify a champion's
Attack Speed will modify their Attack Speed by a set percentage. For all Attack
Speed modifiers, the percentage gained or lost is based on an Attack Cooldown of
1.0, regardless of the champion's current Attack Cooldown. For example a champion
with an Attack Cooldown of 1.2 that receives a +30% Attack Speed buff will have
an Attack Cooldown of 0.9. A champion's Attack Cooldown cannot be raised above 2.5
and cannot be brought below 0.5.
Disrupt - Disruption prevents a champion from using Skills.
When a champion is disrupted, any skill currently being used or primed is canceled.
