Currently you are closing your sub EVENT_HP out before the next hpevent.

sub EVENT_HP
{ 
	quest::emote("quaffs a magical elixir.");
	quest::shout("Now you will die!");
	quest::npcsize(9);
	quest::modifynpcstat("min_hit",70);
	quest::modifynpcstat("max_hit",120);
	quest::setnexthpevent(50);
} #Closing the event early
if($hpevent==50)
{
	quest::shout("Guards!");

my $x = $npc->GetX();
my $y = $npc->GetY();
my $z = $npc->GetZ();
my $h = $npc->GetHeading();

	quest::spawn2(11174,0,0,$x+5,$y+5,$z,$h);
	quest::spawn2(11175,0,0,$x+5,$y-5,$z,$h);
}

Should be:

sub EVENT_HP {
if ($hpevent == 75) {
	quest::emote("quaffs a magical elixir.");
	quest::shout("Now you will die!");
	quest::npcsize(9);
	quest::modifynpcstat("min_hit",70);
	quest::modifynpcstat("max_hit",120);
	quest::setnexthpevent(50);
}
if ($hpevent == 50) {
	quest::shout("Guards!");

my $x = $npc->GetX();
my $y = $npc->GetY();
my $z = $npc->GetZ();
my $h = $npc->GetHeading();

	quest::spawn2(11174,0,0,$x+5,$y+5,$z,$h);
	quest::spawn2(11175,0,0,$x+5,$y-5,$z,$h);
}
}

That should work for ya
