I have not found or seen any posts about it yet but the formula to calculate the explosion damage amount for Critical Hits with this weapon cause an explosion, damaging enemies within .5 tiles for 43 base damage maybe the following:

Base * Hero Ability Damage Percentage / 100 * FORT stuffs (explained below) * Weapon and Hero stuffs (explained below)

​

Base: 43

Hero Ability Damage Percentage / 100 – look in game (on PC go to Command – see all stats)

Fort stuffs :

The sum of Offense and Tech divided by 100 + the sum of any Melee or Ability Damage survivors sets. If you have one set that is providing 5% that's .05

Or

1 + The sum of Offense and Tech divided by 100 + the sum of any Melee or Ability Damage survivors sets. If you have one set that is providing 5% that's .05

Weapon stuffs:

The sum of any Weapon Fixed Perk, Elemental Damage and Hero Perk Damage. If you have an Armaggeddon Axe with a Legendary Damage Perk and a Legendary Energy Perk that's .3 + .2.

​

The mathematical formula though could be either of the following:

Formula #1 Math

43 * Hero Ability Damage Percentage / 100 * (Offense + Tech / 100) + (Melee and/or Ability Damage Survivors) * (100 + Weapon Fixed Perk + Weapon Elemental Damage + Hero Perk Damage) / 100

Or

Formula #2 Math

43 * Hero Ability Damage Percentage / 100 * 1+[(Offense + Tech / 100) + (Melee and/or Ability Damage Survivors)] * (100 + Weapon Fixed Perk + Weapon Elemental Damage + Hero Perk Damage) / 100

Formula #1 Math

Whiteout Fiona in lead HAD 19.38

Offense: 3251

Tech: 3251

4 sets of Ability, 4 sets of Melee damage survivors slotted (8 x .05 = .4)

Legendary Damage Perk 30 % or .3 and Legendary Energy Damage Perk 20% or .2

43 * Hero Ability Damage Percentage / 100 * (Offense + Tech / 100) + (Melee and/or Ability Damage Survivors) * (100 + Weapon Fixed Perk + Weapon Elemental Damage + Hero Perk Damage) / 100

43 * 19.38 * [(3251 + 3251) / 100 + .4] * [(100 + .2 +.3) / 100]

43 * 19.38 * 65.42 * 1.02 (it is really 1.015 but FN rounds up) = 55607.444 (Calculator)

​

Working backwards

55994 / (19.38 * 65.42 * 1.02) = 55994 / 1293.196 = 43.29 base damage

55994 / (19.38 * 65.42 * 43) = 55994 / 54517.102.8 = 1.027 (Weapon and Hero Stuffs)

Formula #2 Math

Whiteout Fiona in lead HAD 19.38

Offense: 3251

Tech: 3251

4 sets of Ability, 4 sets of Melee damage survivors slotted (8 x .05 = .4)

Legendary Damage Perk 30 % or .3 and Legendary Energy Damage Perk 20% or .2

​

43 * Hero Ability Damage Percentage / 100 * 1+[(Offense + Tech / 100) + (Melee and/or Ability Damage Survivors)] * (100 + Weapon Fixed Perk + Weapon Elemental Damage + Hero Perk Damage) / 100

43 * 19.38 * 1+[(3251 + 3251) / 100] + .4 * [(100 + .2 +.3) / 100]

43 * 19.38 * 66.42 * 1.02 (it is really 1.015 but FN rounds up) = 56457.451656 (Calculator)

Calculator 56457

​

Working backwards

55994 / (19.38 * 66.42 * 1.02) = 55994 / 1312.96 = 42.64 base damage

55994 / (19.38 * 66.42 * 43) = 55994 / 55350.4428 = 1.01162 (Weapon and Hero Stuffs)

How did I get these numbers? I ran through a battery of validation tests to determine what variables could affect the explosion damage number.

Validation Tests:

1. Is the Explosion damage affected by Hero Ability Damage Score? Yes
2. Is the Explosion damage affected by Offense and Tech scores? Yes
3. Is the Explosion damage affected by Survivor Squad bonuses? Yes
4. Is the Explosion damage the same regardless of weapon type? Yes
5. Is the Explosion damage the same regardless of material (ore or crystal)? Yes
6. Is the Explosion damage affected by Weapon PL? No
7. Is the Explosion damage affected by Element Damage Perks? Yes
8. Is the Explosion damage affected by Weapon Damage Perks? Yes
9. Is the Explosion damage affected by any Critical Damage Perks? No
10. Is the Explosion damage affected by Hero Perks? Yes

Conclusion(?):

Unfortunately without an official word from Epic, it is still unknown which (if either of these) is correct so use at your own discretion.
