I’ve often noticed that Fastballs have a damage range for any given level but never stayed in the farm long enough to see just what the range was. Normally, I’m just looking to get one that is a particular element and as I progress through the farm notice about where the damage for a decent one should be. Farming Boll yesterday for an OP4 corrosive I got many explosives, a few shocks and few incendiaries before he ever gave up a corrosive. As a result I was able to see the full damage range of the OP4 Fastballs. When I calculated the damage range I was surprised just how big it is. So this morning, went to the Gear Calculator and checked what the variable is that determines a Fastball’s damage. As it turns out, only the “Damage grade” which ranges from grade 3 - 7 impacts the output damage on fastballs. Here’s what the numbers revealed.

**Edit Note:** The total damage numbers in the Gear Calculator for Fastballs are wrong, but the percent change between grades and levels is correct. I confirmed this with my inventory of fastballs, removed the Gear Calculator numbers and replaced the example with observed numbers. On to the results.

The overall damage range from lowest to highest for any element fastball at any level is **14.28%** and is spread in equal quarters throughout the range. For example:

Lvl OP4, grade 7 of 44.155 million damage, minus grade 3 of 38.635 million = 5.519 million damage range. One quarter of the 5.519 million would be added to a grade 3 to get the grade 4 damage value, 38.635 + 1.380 = 40.015 million for damage.

What good is this? For one thing, it can be a quick way to estimate what the damage range is while farming. If you see a difference of approximately 1 million between two fastballs of the same level, you know your looking at a range of about 4 million. The main benefit however is knowing that a 14.28% increase in fastball damage is worth some effort. For my OP4s that equaled a boost of 5,519,376 damage points from a grade 3 to a grade 7. For my Axton, his Bad just got upped.

Also, if your running around with a grade 3 fastball of any level and upgrade it one level higher and to a grade 7, you will add 29% damage. The damage increase between levels is 13%.
