Overflow is basically a glitch that causes negative damage, causing the game to
think that the target has so much HP, it better fix the problem. Instant Death.
Overflow can be attained versus almost all enemies in FF7, with the exceptions
of Ruby Weapon and a Safer Sephiroth at max power. These two enemies have a too
high Defense for the glitch to work.
How does it work? Overflow damage can only be attained by two characters, and
more specifically by only two weapons: Vincent's Death Penalty and Barret's
Missing Score. These two weapons have ridiculous high damage multipliers, which
is the key of access to this glitch. To power up Vincent's Death Penalty, you
need to kill enemies, and the more you kill, the more powerful the weapon.
Barret's Mission Score is powered up by putting as much high AP materia in the
weapon's slots.
The maximum damage multiplier for the Death Penalty is x32, and it's approx.
x25 for the Missing Score. You do not need to have these weapons at max power to
perform overflow, however. It depends on how high the enemy's defense is. The
higher the defense, the more power you need. Emerald Weapon has a Defense of 180
and you'll need quite some power to kill him with Overflow.
Like I said, you don't need the weapons at max power, but say you need approx
2+ million AP in the Mission Score if you throw 4 Hero Drinks on Barret (to
double his attack power). And you'll need approx 15000+ kills on Vincent's
Death Penalty.
Measuring Vincent's kills may be a useful thing to some players. Here's how you
do it the most easy (and only) way:
o Using Everyone's Grudge:
==========================
If you've only just begun with getting kills on Vincent, you can get Vincent hit
by an attack called Everyone's Grudge, used by Master Tonberry in the Crater.
This attack uses this formula: Kills * 10 = Damage. As you can see, you can only
measure up to 1000 kills with this.
o Using Ruby WEAPON:
====================
When you get more and more kills, you can check your kills by doing alot of
math. Do an attack versus Ruby WEAPON. Vincent at Lvl 99, 255 Str, and the
99 Atk Death Penalty will damage Ruby for around 6400 damage. If you do this
damage to Ruby with that Vincent, you'll have around ~12522 kills.
If you're consistently doing 9999 damage to Ruby with the above setup-Vincent,
your kills should be ~20890 or more. That's already enough to kill Emerald with
'Check 2', or in other words with Berserk and Deathblow/Critical Hit.
If you want to measure beyond this, put Vincent under the Frog status before
attacking Ruby Weapon. This will reduce Vincent's damage to 1/4th, so if you
were hitting 9999 before, you will now do 2500 damage (or more, if you had more
kills). At 5000 damage you'll have ~41780 kills.
o Other useful information:
===========================
o If the defense value of an enemy is higher than 421, you can never make the
overflow trick work, ever. Not even with a maxed out Vincent/Death Penalty.
o The max defense an enemy is allowed to have when you're trying to get
overflow with a MAXED Barret, is the value 394. This is good enough for
practically anything but Ruby WEAPON.
o The MINIMUM amount of kills (and here's where it starts to get interesting)
for Vincent's Death Penalty, in order to One Hit KO Emerald WEAPON , is 16896 kills.
o The MINIMUM amount of AP for Barret in order to On Hit KO Emerald WEAPON,
is 1410000 AP.
That's not all that bad, seeing how 3 maxed KOTR Materia would do the trick.
o Furthermore, it's impossible to get overflow if you're not using Berserk or
Deathblow. It *is* possible to get overflow without Hero Drinks (and still
using Berserk & Deathblow), but you would need the ridiculous amount of
60580 kills on a maxed out Vincent. Stick to the above methods...
