I think I tried to bodytype adjustment before with no luck. So, you'll pretty much have to use a different npc that is untargetable.

Your best bet is to have the npc spawn the adds via his quest script and add top player on hate list to their hate list. With them, also spawn a non-targetable version of your encounter npc. Then, run a perl script on untargetable npc. Set a time when he spawns. Have it check for their npc ids in the timer. And if they are not there(thus all dead), he triggers a targetable version of himself. Then use a:

sub EVENT_SPAWN {
$npc->SetHP($npc->GetMaxHP()*75);
}

You could accomplish this with two versions of the npc, but I'd use 3 to keep things cleaner.

As far as the adjustments mid fight, I've used spells and special abilities to do similar when I was hoping to be able to run my project full time. While this script admittedly rough around the edges and could use work, here goes:

sub EVENT_SPAWN {
  	my $x;
	my $y;
	my $z;
	my $h;
	$x = $npc->GetX();
	$y = $npc->GetY();
	$z = $npc->GetZ();
	$h = $npc->GetHeading();
	$stancetype = undef;
	$stancetimer = 0;
	$raid = 0;
	quest::stoptimer("stance");
	$stancetimer = int(rand(10 - 5)) + 5;
	}

sub EVENT_AGGRO {
	if ($raid == 0) {
	$clientencounter = $client->GetName();
	quest::shout("You stupid fools!");
	quest::settimer("stance",$stancetimer);
	quest::settimer("checkengaged",2);
	$raid = 1;
	}
}

sub EVENT_ATTACK {
	if ($raid == 0) {
	$clientencounter = $client->GetName();
	quest::shout("You stupid fools!");
	quest::settimer("stance",$stancetimer);
	quest::settimer("checkengaged",2);
	$raid = 1;
	}
}

sub EVENT_DEATH {
	quest::shout("How could a myrmidon fall to you?!");
}

sub EVENT_TIMER {
	my $check = undef;
	if ($timer eq "checkengaged") {
	if (!$npc->IsEngaged()) {
	$raid = 0;
	$npc->SetHP($npc->GetMaxHP());
	$stancetype = undef;
	$stancetimer = 0;
	quest::stoptimer("stance");
	$stancetimer = int(rand(5 - 1)) + 1;
	quest::stoptimer("checkengaged");
	}
	}
	elsif ($timer eq "stance") {
	$npc->NPCSpecialAttacks(0, 0);
	$stancetype = undef;

}

That is most of the code. Several different "stances". Spawning adds and becoming invulnerable. Switching to defensive mode, offensive mode, and switching immunities.

I have 10-20 of these scripts I was running on my raid encounters on my server. Similar atleast! However, just have not been able to find a stable host/project manager to take over:/
