Magic resistance (or MR) is a stat that all units have, including minions, monsters, and buildings. Increasing magic resistance reduces the magic damage the unit takes. Each champion begins with some magic resistance which may increase with level. You can gain additional magic resistance from abilities, items, masteries, and runes. Magic resistance stacks additively.
All champions begin with 30 base magic resistance. No ranged champions gain magic resistance per level, but many melee champions do, with 52.5 being the maximum magic resistance possible without items, runes, masteries, or ally buffs.
Incoming magic damage is multiplied by a factor based on the unit's magic resistance:
- Damage multiplier = 100 / (100 + MR) if MR ≥ 0
- Damage multiplier = 2 − 100 / (100 − MR) if MR ≤ 0
- 25 magic resistance → ×0.8 incoming magic damage (20% reduction).
- 100 magic resistance → ×0.5 incoming magic damage (50% reduction).
- −25 magic resistance → ×1.2 incoming magic damage (20% increase).
Stacking magic resistance编辑
Every point of magic resistance requires a unit to take 1% more of its maximum health in magic damage to be killed. This is called "effective health."
- Example: A unit with 60 magic resistance has 60% of its maximum health in its effective health, so if the unit has 1000 maximum health, it will take 1600 magic damage to kill it.
What this means: by definition, magic resistance does not have diminishing returns, because each point increases the unit's effective health against magic damage by 1% of its current actual health value whether the unit has 10 magic resistance or 1000 magic resistance.
- Note: Unlike health, increasing magic resistance also makes healing more effective because it takes more effort to remove the unit's health than it does to restore it.

List of champions' magic resistance编辑
- If a summoner leaves the game, their champion gains 1000 armor and magic resistance. This may be to prevent champions like Karthus or Draven from gaining free kills.
- Kayle and Nidalee are the only two champions in the game with 0.75 magic resistance per level growth. All other champions are either 0 or 1.25.
- A level 18 Master Yi with 6 , 3 points in Resistance Resistance, Creeping Death, Bulwark, Aria of Perseverance, Command: Protect Command: Protect, aura, Glyphs, Seals, Marks and Quintessences of Shielding, and Meditate active will give a total of approximately 1086 MR. Having an enemy Trundle with the same items and support use Agony on Master Yi will yield a total of approximately 1329 MR or 93% reduction.
- Swapping out Orianna or Mordekaiser for Trundle on the team of Master Yi and saving the Active buffs for the Trundle result in a 916.32 Master Yi, 1244.48 Enemy Trundle and 1378.56 Allied Trundle if the Allied Trundle uses Agony on the Enemy Trundle. This is the highest amount of Magic Resistance obtainable without exploiting the disconnection bonus.
- A disconnected level 18 Garen with the same items, runes, masteries and support as the above Master Yi will give a total of approximately 2144 MR after applying Courage for 95.5% reduction. Without the bonus Magic Resistance from leaving, Courage does not quite equal Meditate. This is the highest possible amount of Magic Resistance.
- Unlike the Master Yi example, a similarly kitted and supported Trundle using Agony on the Garen will actually result in a reduced 1858 Magic Resistance on the Trundle.
