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 does not have a threshold; while the buff is up, the unit takes literally no HP loss from any damage source, and damage-triggered effects on the unit (e.g. on-hit shred application that requires landing damage) do not fire either. 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

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. Many TFT items and trait actives stack the first two — granting 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, and resistance shreds (Armor / Magic Resist reductions) and anti-heal still apply because they are debuffs, not damage. The practical consequence: a unit that is invulnerable but not also CC-immune can be stunned mid-window, lose the ability to cast or attack, and walk out of the buff with debuffs already on it. 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 healing and health costs are not prevented by invulnerability — heals from allies, regen, omnivamp on a teammate, and shield application all still go through and stack normally on the invulnerable target. Self-buffs (attack speed, ability power, durability stacks) also continue to apply. The window is therefore often used as a free top-up: the unit takes no damage, builds shields, and gets healed simultaneously, then 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. Invulnerability zeroes true damage along with everything else, and no TFT item, trait, or augment is currently documented as ignoring invulnerability. The wiki only lists narrow LoL-summoner-mode exceptions (Ivern's Friend of the Forest for technical reasons, Nexus Obelisk to handle base damage) — neither has a TFT analogue. 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. The same logic applies the other way: hitting an invulnerable unit that has thorns is a clean lose-lose for the attacker, since 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, and multiple durability sources stack multiplicatively (50% × 50% lands at 75% reduction, not 100%). Durability shaves damage; it never zeroes it, and it does not protect against true damage. Invulnerable is binary — for the window it's up, the unit takes 0 damage from every source including true damage. 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 (burns, bleeds) that try to tick while the unit is invulnerable deal 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. Practically, invulnerable is a clean window of total safety, but as soon as it ends the unit is fully exposed — plan finishers and re-positioning around the duration's exact endpoint.
