Now for the Z-Souls
Last place
I'll use all my strength to kill you
386 damage >>> 10% increase at max ki
Hey, it's a rank 2 soul and also regenerates Ki. What did I even expect

Fifth place:
Guess we should fuse into Vegito...
400 damage >>> 13.6% increase when transformed and reinforced.
Hey, it also raises all other stats apparently, just not good for pure punchy builds.

Fourth Place:
Transforming doesn't fix everything
408 damage >>> 16% increase when full ki
Also increases defense when stamina is full. But be honest, it never is.

Third Place:
You can't win
418 damage >>> 18% increase when full ki
If you add this to the fact you just guard when your health is full. You have a beastly Z-Soul.

You can use this to Pose in close quarters, you might be able to confuse them long enough to finish your pose.
(Incase you can't block while posing, which sounds pretty logical, it's pretty bad for this type of build)

Secod Place:
Don't you see the strength difference here?
439 damage >>> 25% increase when full ki
Too bad we can't make use of the "Recharge large amounts of Ki upon taking damage" as we'll usually be full ki.

Grand Winner:
Like I predicted,
Double it, but go no higher!
468 damage >>> 33% increase when reinforced
The extra damage you do thanks to this zsoul is ridiculous. However, the health drain from it is just as ridiculous. I'd only recommend this for fun gimmicky builds, otherwise you'll find yourself draining to your death.

Maximum light punch damage, full +5 basic attack armor, full ki, kaioken x20, Justice Pose, Double it but go no higher.

a whopping 521 damage >>> 124% damage increase!
