It was not too bad, this did it.
Code:
my @clientlist = $entity_list->GetClientList();
foreach $ent (@clientlist)
{
$ent->CastSpell(2570, $ent);
}
my @npclist = $entity_list->GetNPCList();
foreach $ent (@npclist)
{
$ent->CastSpell(2570, $ent);
}
The only downside is that it looks like they are casting it themselves, which they are. This is the only way I figured for it to work. If you think of any other way let me know.
