In the description

This is part of it:

With pyroplus you get protection from Lava as well as Fire! Swim through lava and walk in fire with no more fear! Please note there is no way to turn this off; once you apply this feature to your account you will always be immune to Lava/Fire deaths!

This is not true, later in the description, you can do /cheat, etc to turn it off, thus making part of the description false.
