An unsuspecting individual dies in the real world, only to find out they've won some lottery and been reborn in the world of Naruto with the Gamer System. The only problem is that this person doesn't know about the world of Naruto. Sure, he's watched some of the anime, but that's everything. How will this unprepared and unknowledgeable person survive in the brutal world of Shinobi? --------- An answer to a commonly asked question (credit for the question goes to HighV.)-------- People have a hard time with percentile. A simpler conversion and explanation is this. (100% = 1.00) When you see this, they're the same thing. When you multiply a number, let's say 2, by 1 or 1x. It stays as 2, 100%, or 1.00. (This doubles the damage in a gamer-type story like this.) If it's below 100% or 1.00, it looks like this. (89% = 0.89) If you're multiplying, let's say 200, by 0.89 or 89%. It becomes 178. This is why 50% or 0.50 is only half the damage increase. (1000 x 0.50 or 50% = 500), so you increase the base 1000 damage by half the amount, which is 500. Bringing the total damage up to 1500.Now, to your question, how does a -200% decrease in physical damage work if 100% is suppose to stop all damage? Simple, let's say someone deals 2500 points of damage to Fuyuki. With a -200% or just simply stated as a 200% damage reduction, this is how it looks. (2500 divided by 2.00 or 200% = 1250) When you're reducing damage instead of increasing it, you use division instead of multiplication.Here's how it looks the other way, with a damage increase. Let's say Fuyuki does 3000 damage with a Ninjutsu, and he has a 400% increase in damage with a buff from one of his skills. This is how it looks. (3000 x 4.00 or 400% = 12,000) Remember, every increment of 100% is actually 1.00 times the damage. Which means dealing 100% damage actually means doubling the base damage.Hope this helps! I'm no math mathematician, but this is how it works in this story.
