Lava/Killbrick

You can find the Lava/Killbrick in the advanced section of the game.

Overview
This brick is one of the most essential brick in obbies, as it kills players, resetting their character, and forcing them to respawn at a checkpoint or at the start.

Properties
You can change this blocks damage, color, and turn off collision and cast shadow. Remember, a player has 100 Hit points, so setting the damage to 50 means it will only decrease the Health bar to 50. It was most likely here at the start of the game.

Trivia

 * Its default appearance is red, and default damage is 100.
 * It is the only way to kill a player not including falling into the void.
