In Roblox TSB, iframes usually means invincibility frames : a short period where your character can’t be hit after certain moves, dodges, awakenings, or cutscenes. They’re used to stop instant follow-up damage and make some attacks or animations safer to use.

What it does

  • Makes you temporarily unable to take damage.
  • Can protect you during specific move animations.
  • Often appears on ultimates, finishers, and some special skills.

In TSB specifically

  • Some moves give normal iframes, meaning attacks just pass through and don’t hit you.
  • Some effects can act like “damage iframes,” where touching or attacking the target can still punish the attacker.
  • Not every move has iframes, and players often argue about which ones should or shouldn’t.

Simple example

If you pop a move with iframes right as someone attacks you, their hit may go through without damage, letting you survive the punish window and counter back after the animation ends.

Extra note

This is different from Roblox UI “frames,” which are interface containers, not combat protection.

TL;DR: In TSB, iframes are brief cannot-hit-me windows that make certain moves, awakenings, and cutscenes safer.
