Shields in LoL: why they’re worth more on a tank
A shield isn’t just “temporary health”: because it absorbs damage after your resistances, it’s worth more the more armored you are. A 300 shield on a tank with armor blocks twice the damage it does on a paper champion. Here’s why.
A shield is amplified by your resistances
The key thing almost no one accounts for: resistances mitigate damage BEFORE the shield absorbs it. Damage is first reduced by your armor (or magic resist) and only then taken off the shield. That’s why a shield is “worth more” the more armored you are.
The chart shows it with the real engine: a 300 shield blocks 300 raw physical damage if you have 0 armor… but 600 if you have 100 armor, and 900 with 200. The shield multiplies by your resistances exactly like health does: it’s temporary effective health. It’s the same principle as in health vs resistances.
Practical takeaway: shields and resistances amplify each other. A tank receiving a shield from an ally takes a ton; the same shield on a defenseless champion blocks far less. That’s why shield supports shine on frontliners.

A shield is amplified by your armor and magic resist just like health. Normal shields also block true damage, and grievous wounds don’t touch them.
Normal, magic and physical: and true damage
There are three shield classes. The normal shield (grey) absorbs any damage type: physical, magic and true. The magic shield (purple) only absorbs magic damage. The physical shield (orange) only absorbs physical damage. Knowing the shield’s color tells you which damage it doesn’t help against. If you’re unsure about the damage types, review them first.
The most valuable detail: the normal shield blocks true damage, which ignores all resistances. It’s one of the few things that stop true damage (along with invulnerability). That’s why a well-timed shield can save someone from a combo that would “pierce” any armor.
And unlike healing, grievous wounds do NOT reduce shields (see the healing and antiheal guide). What does cut them is Serpent’s Fang’s anti-shield effect, which reduces the value of shields on enemies you hit: the specific answer against teams that shield a lot.
| Shield type | Physical | Magic | True |
|---|---|---|---|
| Normal (grey) | ✓ | ✓ | ✓ |
| Magic (purple) | — | ✓ | — |
| Physical (orange) | ✓ | — | — |
Normal shields (grey) absorb all three damage types, including true: they’re one of the few things that block it. Magic shields (purple, like Karma’s) only stop magic damage, and physical ones (orange, like Braum’s W or Steadfast Presence) only physical. A specific shield used well blocks far more than a normal one of the same size against that type.
How to use them: timing and shield power
A shield is all about timing: since it’s temporary and gets spent, dropping it right before the big hit uses it fully, while throwing it too early or late wastes it. Against a burst combo, the shield that lands at the exact moment can negate more effective health than any defensive item.
Heal and shield power increases the size of the shields you apply (not the ones you receive). It’s a key enchanter-support stat: it makes every shield you hand out block more damage, and it stacks with the resistances of the ally receiving it.
In practice: a shield on an armored frontliner, at the right moment, is one of the most cost-effective defensive plays in the game. Test how much damage your shield absorbs against different resistances in the Mitigation Lab and compare builds in Versus.
FAQ
Do shields block true damage?
Normal (grey) shields do: they absorb physical, magic and true. Magic (purple) shields only block magic damage and physical (orange) only physical. The normal shield is one of the few things that stop true damage.
Do grievous wounds reduce shields?
No. Grievous wounds only reduce healing and regeneration, not shields. The effect that does cut shields is Serpent’s Fang’s anti-shield, which reduces the value of shields on enemies you hit.
Why is a shield worth more on a tank?
Because resistances reduce damage before the shield absorbs it. A 300 shield on 100 armor blocks 600 raw physical damage, not 300. The more armor or magic resist the receiver has, the more raw damage the same shield blocks.
