# ============

# hash of stuff we want to possibly randomize, and by how much.
# this setup allows you to tweak chances of and ranges of scaling each stat
# it also allows you to keep the logic below a little cleaner.
my $target = {
	# strength
	str => {
		# chance at randomization defined here (25%)
		randomize => do { rand 100 > 75 },
		# 'normal' scaling is a range of 110-130% at a 75% chance
		# 'critical' scaling is a range of 130-200% at a 25% chance
		modifier  => do { rand 100 > 75 ? randRange(10, 25) : randRange(25, 75) },
		# workaround since each stat has its own method of retrieval
		accessor  => do { $npc->GetSTR() },
		# arbitrary here, but it's a good idea to have the ones below
		cleanup   => do { $npc->Emote("snarls menacingly...") },
	},
	# intelligence
	_int => {
		randomize => do { rand 100 > 75 },
		modifier  => do { rand 100 > 75 ? randRange(10, 30) : randRange(30, 100) },
		accessor  => do { $npc->GetINT() },
		cleanup   => do { $npc->SetMana($npc->GetMaxMana()) },
	},
	# wisdom
	wis => {
		randomize => do { rand 100 > 75 },
		modifier  => do { rand 100 > 75 ? randRange(10, 30) : randRange(30, 100) },
		accessor  => do { $npc->GetWIS() },
		cleanup   => do { $npc->SetMana($npc->GetMaxMana()) },
	},
	# stamina
	sta => {
		randomize => do { rand 100 > 75 },
		modifier  => do { rand 100 > 75 ? randRange(10, 30) : randRange(30, 100) },
		accessor  => do { $npc->GetSTA() },
		cleanup   => do { $npc->Heal() },
	},
};

# for each stat listed in the table of targets...
foreach my $stat (keys %$target)
{
	# skip stat if we don't roll a chance to randomize it
	# TODO: further modify chances based on race/class
	next unless $target->{$stat}->{randomize};

	# get the current value of the stat we are looking at
	my $current = $target->{$stat}->{accessor};

	# roll for and retrieve the modifier to use to scale the stat
	my $scale = $target->{$stat}->{modifier};
	
	# stat scaling calculation happens here
	my $modified = $current + int($current*(rand $scale/100));
	
	# change applied
	$npc->ModifyNPCStat($stat, $modified);
	
	# do any cleanup defined for the current stat
	$target->{$stat}->{cleanup} if defined $target->{$stat}->{cleanup};

annnnnd if you put this in your global_npc.pl

*Mob::Blast = sub {
	my $self = shift;
	$self->SetMana($self->GetMaxMana());
	$self->Emote("shimmers slightly.");
};

you can do this

$mob->Blast()

when you want the equivalent of this for mana

$mob->Heal()

which is currently this

$mob->SetMana($mob->GetMaxMana())

it will work for any object that is derived from the Mob class.
