What happens in the patched version of 2 Worlds if the final boss is killed by peasents

In this speedrun, we see the game ending in under 3 minutes, when the player provokes the final boss to attack some villagers, who in turn maul him to death.

The player mentions that he's using a non-patched version of the game because this was fixed later. I am not planning to buy this game any time soon to try myself so what happens in the patched version of the game if the same trick is attempted.
