Q: Invulnerable, untargetable, and stasis — what's the difference?

They are three different protection layers. Invulnerable means the unit takes 0 damage but is still a valid target. Basic attacks and abilities can still pick it. They just deal nothing. Untargetable means the unit cannot be selected as a target by basic attacks or new abilities at all. But already-applied damage-over-time effects continue ticking on it. Stasis is the strongest. The unit is invulnerable AND untargetable AND cannot move, attack, cast, or use items for the duration. Note: Many TFT items and trait actives stack the first two. They grant invulnerable plus untargetable in the same window, for full protection.

Q: Can an invulnerable unit still be stunned, slowed, or shred?

Yes. Invulnerable specifically blocks the damage layer . It does not block the disable or debuff layer. Stuns , knock-ups, slows , and chills still land normally on an invulnerable unit. Even resistance shreds (Armor / Magic Resist reductions) and anti-heal still apply. They are debuffs, not damage. The practical consequence: a unit that is invulnerable but not also CC-immune can be stunned mid-window. It then loses the ability to cast or attack, and walks out of the buff with debuffs already on it. Note: To block CC you need a separate CC-Immune effect.

Q: What happens when invulnerability expires mid-combat — do DoTs tick through the window?

The window ends and damage lands normally on the next tick . The buff does not extend, refund HP, or grant a grace period afterward. Damage-over-time effects such as burns and bleeds do not tick through the window: While the unit is invulnerable, each tick deals 0 , like everything else. The damage is not stored or paid back when the buff drops. Contrast this with untargetable, where already-applied DoTs keep ticking through. Note: Invulnerable is a clean window of total safety. As soon as it ends, the unit is fully exposed. Plan finishers and re-positioning around the duration's exact endpoint.

Question 1

What does invulnerable actually mean — does it block true damage too?

Accepted Answer

Yes. Invulnerable is a binary status that reduces all damage taken to 0.

Physical, magic, and true damage are all zeroed for the duration.
It is not a percent reduction, and it has no threshold.
While the buff is up, the unit takes literally no HP loss from any damage source.
Damage-triggered effects on the unit do not fire either. One example is on-hit shred application that requires landing damage.

Note: Once the duration ends, the unit takes damage normally on the very next attack.

Question 2

Invulnerable, untargetable, and stasis — what's the difference?

Accepted Answer

They are three different protection layers.

Invulnerable means the unit takes 0 damage but is still a valid target. Basic attacks and abilities can still pick it. They just deal nothing.
Untargetable means the unit cannot be selected as a target by basic attacks or new abilities at all. But already-applied damage-over-time effects continue ticking on it.
Stasis is the strongest. The unit is invulnerable AND untargetable AND cannot move, attack, cast, or use items for the duration.

Note: Many TFT items and trait actives stack the first two. They grant invulnerable plus untargetable in the same window, for full protection.

Question 3

Can an invulnerable unit still be stunned, slowed, or shred?

Accepted Answer

Yes. Invulnerable specifically blocks the damage layer. It does not block the disable or debuff layer.

Stuns, knock-ups, slows, and chills still land normally on an invulnerable unit.
Even resistance shreds (Armor / Magic Resist reductions) and anti-heal still apply. They are debuffs, not damage.

The practical consequence: a unit that is invulnerable but not also CC-immune can be stunned mid-window. It then loses the ability to cast or attack, and walks out of the buff with debuffs already on it.

Note: To block CC you need a separate CC-Immune effect.

Question 4

Can invulnerable units still be healed, shielded, or buffed during the window?

Accepted Answer

Yes. The wiki is explicit that invulnerability does not prevent healing or health costs.

All of these still go through and stack normally on the invulnerable target:

Any heals from allies.
Regen.
Omnivamp on a teammate.
Every shield applied to it.
Self-buffs such as attack speed, ability power, and durability stacks.

Note: The window is therefore often used as a free top-up. The unit takes no damage, builds shields, and gets healed at the same time. Then it re-enters the fight at higher effective HP than it left at.

Question 5

Does anything in TFT bypass invulnerability — can true damage or executes get through?

Accepted Answer

No documented TFT-side bypass exists.

Invulnerability zeroes true damage along with everything else. No TFT item, trait, or augment is currently documented as ignoring invulnerability.

The wiki lists only two narrow exceptions. Both come from League's main map, and both exist there for technical reasons. One is a champion passive and one is a base structure. Neither has an analogue here.

Note: Treat invulnerable as a hard wall while it lasts. The only way the carry dies during the window is if the duration runs out and damage lands on the next tick.

Question 6

Does damage-reflection still trigger when attacking an invulnerable target?

Accepted Answer

Yes. The wiki is explicit: an invulnerable champion with thorns-style reflection will still reflect damage.

The basic-attack event still fires when the attack hits. The reflection effect keys off the hit event, not off damage actually being dealt. So the attacker eats the magic-damage reflect even though their attack did nothing.

Note: The same logic works the other way. Hitting an invulnerable unit that has thorns is a clean lose-lose for the attacker. They spend a full attack cycle and pay reflect damage for zero return.

Question 7

How is invulnerable different from durability?

Accepted Answer

Different shape, different power.

Durability is a percent damage reduction:

A 30% durability buff means the unit takes 70% of incoming damage.
Multiple durability sources stack multiplicatively. 50% × 50% lands at 75% reduction, not 100%.
Durability shaves damage. It never zeroes it.
It does not protect against true damage.

Invulnerable is binary. For the window it is up, the unit takes 0 damage from every source, including true damage.

Note: Durability is the gradient version of damage reduction. Invulnerable is the on/off switch.

Question 8

What happens when invulnerability expires mid-combat — do DoTs tick through the window?

Accepted Answer

The window ends and damage lands normally on the next tick. The buff does not extend, refund HP, or grant a grace period afterward.

Damage-over-time effects such as burns and bleeds do not tick through the window:

While the unit is invulnerable, each tick deals 0, like everything else.
The damage is not stored or paid back when the buff drops.

Contrast this with untargetable, where already-applied DoTs keep ticking through.

Note: Invulnerable is a clean window of total safety. As soon as it ends, the unit is fully exposed. Plan finishers and re-positioning around the duration's exact endpoint.
