Is it possible to kill a warden in hardcore mode?

This 10‑hour stream explores whether the player can kill the Warden, Minecraft's strongest mob, in hardcore mode. The Warden has 250 hearts and deals massive damage. The player cannot use companions such as wolves or golems, and is not using a mace, which is not prohibited. The challenge is to defeat the Warden in a single stream. The video uses complementary shaders.
