Quick question, Damaging an NPC via Signal when another mob is killed

[Astal]

You can send a signal from one npc to another correct?

If so am I using $npc->SetHP correctly here? Can you have a -# inside the brackets or do you have to do that a different way?

#azog mon
sub EVENT_SIGNAL {
	quest::shout("Signal Sent");
	$npc->SetHP(-100000); #damage azog mon by 5%
}

#hand
sub EVENT_DEATH {
quest::signal(999430, 0); #signal azog mon to get damaged
}
