What counters Magic Resist
Frequently asked questions
-
What is Magic Resist (MR) and how does it work in TFT?
Magic Resist is the magic-defense stat that reduces incoming magic damage. Each point of MR multiplies effective HP against magic damage by 1 + MR/100, so post-mitigation damage equals raw damage × 100/(100 + MR). That works out to 50 MR ≈ 33.3% magic damage reduced, 100 MR = 50% reduced — and the EHP curve scales linearly with no diminishing returns. MR does nothing against physical damage, and true damage ignores it entirely — including Burn, which deals percent-max-HP as true damage.
-
What's the difference between Magic Resist and Armor — and between Shred and Sunder?
Armor reduces incoming physical (AD) damage; Magic Resist reduces incoming magic (AP) damage. Both use the same reduction formula — R / (100 + R) — just applied to different damage types. The reduction debuffs mirror that split: Sunder reduces a target's Armor, Shred reduces a target's Magic Resist. Both are percent-based reductions, not flat. Duration varies by source — some applications are timed (a few seconds after a hit), others persist as auras while a condition holds.
-
When mixing flat and percent MR reduction, what is the order of operations?
Flat MR reduction is applied to the MR value first, then percent Shred operates on the remaining value, then the resistance formula runs against that final MR. Damage amplifiers — effects that read 'deals X% more damage' — apply post-mitigation in TFT, after the MR formula resolves. The practical consequence: stacking flat reduction first then percent Shred gets diminishing efficiency from the Shred (it operates on a smaller MR value), and resistances cannot go below 0 — flat reduction past zero is wasted.
-
Are there diminishing returns on stacking Magic Resist?
No — in effective-HP terms, every point of MR adds a fixed slice of EHP regardless of how much MR you already have. The formula EHP = HP × (1 + MR/100) means going from 0 to 100 MR doubles your effective HP versus magic damage (1.0× → 2.0×), and another +100 MR adds the same fixed slice on top (2.0× → 3.0×). The percentage-reduction curve flattens, but EHP scales linearly. What stacking only MR leaves you exposed to is physical damage (which Armor handles) and true damage, which ignores both resists. Layer MR with Armor and HP.
-
How do Shred and other Magic Resist reduction effects stack with each other?
The Shred keyword does not stack. When multiple Shred sources hit the same target, they don't add together — Riot's exact patch-note phrasing is 'this effect does not stack'. Two 30% Shreds don't combine into 60%; only one Shred is active at a time. Note that a few champion abilities and items apply flat MR reduction (a small fixed value, e.g., −X MR per hit) — those follow different stacking rules than the percent Shred keyword, even when their tooltip text also reads 'Shred'.
-
Can a unit's Magic Resist go below zero, and does that amplify damage taken?
No — not in current TFT. Resistances are floored at 0. Once Shred and other MR-reduction effects bring a unit to 0 MR, any further reduction is wasted: incoming magic damage is fully unmitigated (essentially true damage), but it isn't amplified. The reduction multiplier 100 / (100 + MR) tops out at 1.0×. This is a deliberate divergence from base League of Legends, where negative resistances can amplify damage: TFT patched the negative-resist edge cases out of champion kits years ago, and the floor at 0 has held across every set since.
Sources
-
Does Magic Resist help against true damage or Burn ticks?
No. Magic Resist only reduces incoming magic damage, so true damage of any kind passes through it untouched. Burn is a clear example — its damage-over-time tick is dealt as true damage based on a percentage of the target's maximum Health, so neither MR nor Armor mitigates it. MR also doesn't reduce physical damage. Because MR is purely a damage-reduction stat, a unit with stacked MR but a thin Health pool can still be melted by any source tagged true damage in its tooltip.
-
Does TFT have Magic Penetration like League of Legends?
No — TFT does not expose a 'Magic Penetration' stat the way League does. There is no item, trait, or buff that grants flat or percent magic penetration as a holder-side stat. Instead, TFT reduces a target's effective Magic Resist through Shred, a debuff applied to the target (most commonly via on-hit item effects, certain trait actives, and ability scripts). Damage amplifiers — clauses that increase outgoing damage by a percent — are a separate mechanic and don't reduce MR; they stack alongside Shred rather than replacing it.
