You had multiple syntax issues going on. This should work fine:

sub EVENT_SAY {

	if ($text =~/hail/i && $ulevel >= 45)
	{
		my $Group = $client->GetGroup();
		if($Group)
		{
			$Group->CastGroupSpell($npc, 2570);
		}
		else
		{
			my $GetPlayerID = $client->GetID();
			quest::selfcast(2570);
		}
		quest::say("Incoming KEI for $name");
	}

}

I suggest reviewing the changes I made so you can learn what you did wrong.
