Your mistake in this sub: 
sub Char{ 
  my $char=400;
  my $hp= $char - int(rand(20)); 
  print $hp ; 
}

is that you re-initialise the character's hit points to 400 every time you call it. The first line sets their hit points to 400, and then the next line subtracts a random number from it. Why do you need this in a function at all? Isn't it easier to just do 
$hp= $hp-int(rand(20));

instead of calling a function?
