League of Legends Wiki: Magic Resistance and Damage Calculations
Magic resistance (MR) in League of Legends reduces incoming magic damage by a percentage. Here's everything you need to know:
Magic Resist Basics:
- Stacks additively
- Each champion has base MR that increases per level
- Base + bonus MR = total magic resistance
- Gold value: 20 per point
How MR Works:
- Damage reduction formula: Post-mitigation damage = Magic damage × [100/(100 + MR)]
- Each point of MR increases effective health by 1% against magic damage
- Example: 100 MR = 50% magic damage reduction
MR vs Health:
- Optimal balance: Health = 6.75 × (MR + 100)
- Health is more efficient early game
- MR makes healing more effective
- Consider enemy damage composition when choosing between MR and health
Base MR Values:
- Most melee champions: 32-66.85 (based on level)
- Most ranged champions: 30-52.1 (based on level)
Ways to Increase MR:
- Items (Force of Nature, Hullbreaker, etc.)
- Champion abilities
- Runes (Aftershock, Conditioning)
- Neutral buffs
Important Considerations:
- Enemy magic penetration
- True damage presence
- Champion kit synergies
- Team composition
- Healing abilities
For optimal efficiency, aim to maintain roughly 100 more health points than magic resistance, while considering gold efficiency and specific game situations.
