The named Shred keyword works like this.
- It cuts Magic Resist by a percentage, commonly 30%.
- It lasts for a duration.
- With some sources it lasts for the rest of combat.
- It does not stack.
- A second Shred source on the same target adds nothing.
Other sources instead subtract a flat number of Magic Resist. Those work differently.
- The cut lands per hit or on a timer.
- These cuts keep adding up.
- The floor is 0 Magic Resist.

Frequently asked questions
-
What is Shred in TFT and how much Magic Resist does it remove?
Shred is a target-side debuff. It reduces a unit's Magic Resist by a percentage for a duration.
The most common keyword application is 30% Shred. Riot item text reads 'Damage from attacks and Abilities 30% Shred the target for 5 seconds.'
The percent operates on the target's current MR (Magic Resist). Against a 100-MR tank, 30% Shred cuts MR to 70. That raises the magic damage it takes for the rest of the window.
Note: Shred is the inverse of Magic Resist, the way Sunder is the inverse of Armor.
-
What's the difference between Shred and Sunder?
Sunder reduces a target's Armor. Shred reduces a target's Magic Resist.
They mirror each other. Both sit on top of the same R / (100 + R) damage-reduction curve, just on opposite damage types.
- Pick Sunder when your team's primary damage is physical (AD, attack damage).
- Pick Shred when your primary damage is magic (AP, ability power).
Note: High-elo coaches treat one of the two as a mandatory item every game by Stage 4–5. Which one you build is dictated entirely by your damage type, not by personal preference.
-
Does Shred stack? If two units apply Shred to the same target, do they combine?
No. Shred does not stack.
Two 30% Shreds on the same target still leave it at 30% reduced MR. Not 60%, and not 51% compounded. Riot's item text explicitly reads 'This effect does not stack.'
When multiple sources land:
- Only one Shred is active at a time.
- The longer remaining duration wins.
- Reapplying refreshes the timer instead of adding a new layer.
Note: A second Shred holder is wasted item slots if it hits the same target your first holder already debuffed.

What about flat Magic Resist reduction — does that stack with Shred?
Yes. Flat Magic Resist reduction stacks with Shred.
Flat MR reduction (a fixed value like −15 MR from a champion ability) is a separate effect from the percent Shred keyword. It follows different stacking rules: multiple flat reductions can layer onto the same target.
The order of operations matters:
- Flat reduction is subtracted from MR first.
- Then percent Shred operates on the remaining MR.
- Then the resistance formula runs.
Note: Stacking flat reductions before Shred makes the Shred itself smaller in absolute terms. But the combined MR cut is still larger than either source alone.

-
Is Shred mandatory every game, or only against tanky enemies?
Every game, according to top-finishing players. They treat Shred or Sunder as a mandatory item, not a situational pick.
You pick whichever of the two matches your damage type. The reasoning is leverage. At high enemy resist totals, a 30% cut is worth roughly a 25%+ damage increase for your entire board. That scales better than a third raw-damage item on a single carry.
Note: Standard timing is built by Stage 4, at the latest Stage 5-1. Put the holder on the same flank as your primary carry, so the debuff lands on the frontline being attacked.
-
Can Shred push Magic Resist below zero to amplify magic damage?
No. TFT floors resistances at 0.
Once Shred and any flat reductions bring a target to 0 MR, further reduction is wasted. The target takes full unmitigated magic damage, but the damage is not amplified above 100%.
Note: This differs from base League of Legends, where some champions historically pushed MR negative for an amp effect. TFT closed that door years ago. Riot patched the specific negative-resist edge cases out of the relevant abilities. The floor-at-0 rule has held across every set since.

Does Shred do anything against true damage?
No. Shred does nothing against true damage.
Shred only affects how much magic damage a target takes, by lowering its Magic Resist. It has no effect on physical damage. True damage ignores resistances entirely.
The TFT wiki's true-damage page is explicit. It says true damage 'ignores resistances (armor and magic resistance), damage reduction, and damage amplification.'
That means Burn ticks cut through a Shredded target at exactly the same rate as an un-Shredded one. Burn ticks are dealt as a percentage of max Health in true damage.
Note: Shred is purely a magic-damage amplifier.
-
Is Shred a debuff on the target or a stat on the holder?
A debuff on the target. Shred is target-side, not a holder-side stat.
There is no 'Magic Penetration' stat in TFT. The game does not expose a buff that adds penetration to your unit's outgoing damage. Instead, the Shred holder applies a debuff to whichever enemy it damages. That debuff lives on the enemy until its duration runs out.
Note: It does not matter how high your unit's AP (ability power) is when calculating Shred. What matters is whether your unit consistently lands hits or ability damage on the target you want softened.
