In Roblox Lost Souls , blocking is usually done with the game’s combat control rather than a separate Roblox-wide setting. A common setup is to hold the block key when an enemy attack is coming, then release it after the hit window passes.

What to try

  • Look for a block or guard key in the game’s controls menu.
  • On PC, many Roblox combat games map block to F , Q , Right Mouse , or another combat key, depending on the experience.
  • If the game has a stamina or posture system, blocking may only work while you have enough stamina.

If you mean Roblox blocking

Roblox’s platform-level block feature is different: it blocks another user from interacting with you, and you can do it from their profile, the in- experience player list, or the Esc menu on supported devices.

Fast check

  • Open Settings or Controls in Lost Souls.
  • Check the keybinds for Block , Guard , or Parry.
  • If there’s no visible keybind, the game may use a tutorial prompt or an on-screen combat hint.

One caution

I couldn’t verify a Lost Souls-specific official control guide from the available results, so the safest answer is to check the game’s own controls screen or community guide for the exact keybind.
