RE: Boss Damage stacking.

Behold, Southperry. I'm here to help you bust your myths, opinions, and facts or something. Basically this is my attempt at seeing if boss damage truly stacks. I will, however, be needing some assistance on the math, just to see if I'm getting the formulas right.

 Damage Formula

Damage formula: [((Damage Range*Skill%)*Critical)*((1 - PDrate) + (PDrate * (ignore defense total))]* DamageInc

 Kataras and Damage range

 Mathematics

Variables:
Damage Range(s):
28188~40269
21883~31262
Critical Damage: 1.5x
Ignore PDR: 0%, Total PDR: 25% (Dojo monsters have 25% PDR, correct me on this)
Total % Boss Damage: 60% (30% on Dagger, 30% on Katara)
Total % Total Damage: 8% (8% total damage on VIP Katara)
Skill %: 920%, assuming it combines both Katara + Dagger damage. (Sudden Raid)

 Regular Damage with Sudden Raid, assuming 8% total damage.

112 Katara:
Minimum: 28188*920%*.75*1.08 = 210057
Maximum: 40269*920%*.75*1.08 = 300085
47 Katara:
Minimum: 21883*920%*.75 = 150993
Maximum: 31262*920%*.75 = 215708

 Assuming 30% boss damage, ignoring 8% total damage

112 Katara:
Minimum: 28188*920%*.75*1.3 = 252846
Maximum: 40269*920%*.75*1.3 = 361213
47 Katara:
Minimum: 21883*920%*.75*1.3 = 196291
Maximum: 31262*920%*.75*1.3 = 280420

 Assuming 60% boss damage(additive), ignoring 8% total damage

112 Katara:
Minimum: 28188*920%*.75*1.6 = 311196
Maximum: 40269*920%*.75*1.6 = 444569

 Assuming 69% boss damage (multiplicative), ignoring 8% total damage

112 Katara:
Minimum: 28188*920%*.75*1.69 = 328700
Maximum: 40269*920%*.75*1.69 = 414932

 Assuming 30% boss damage, whilst multiplying by 8% total damage

112 Katara:
Minimum: 28188*920%*.75*1.3*1.08 = 273074
Maximum: 40269*920%*.75*1.3*1.08 = 390110

 Assuming 60% boss damage, whilst multiplying by 8% total damage

112 Katara:
Minimum: 28188*920%*.75*1.6*1.08 = 336091
Maximum: 40269*920%*.75*1.6*1.08 = 480135

Damage testing gets too tedious, especially with the 1 minute cooldown of Sudden Raid.

 Conclusion

407262 damage. Mano isn't weak to fire.
Looking at our previous results, you'll see that

 Assuming 30% boss damage, ignoring 8% total damage

112 Katara:
Minimum: 28188*920%*.75*1.3 = 252846
Maximum: 40269*920%*.75*1.3 = 361213
47 Katara:
Minimum: 21883*920%*.75*1.3 = 196291
Maximum: 31262*920%*.75*1.3 = 280420

 Assuming 30% boss damage, whilst multiplying by 8% total damage

112 Katara:
Minimum: 28188*920%*.75*1.3*1.08 = 273074
Maximum: 40269*920%*.75*1.3*1.08 = 390110

This damage number, is larger than both of those calculations. Meaning, in short, that it must have stacked with 30% boss damage. This isn't the only instance of it occurring.

412011.

However, there could still very well be some error to this as I haven't completely confirmed anything as of yet. I've just begun testing and Dual Bladers in general have some pretty f`ucked up formulas. Chances are I'll test this after chaos as well.

Basically speaking, I couldn't test this anymore. Honestly I can't, the one minute cooldown is the biggest pain in the ass known to man. So I couldn't find out if 60% boss damage stacked with 8% total damage, although I'm assuming it does.

tl;dr
Boss damage stacks, and here's mathematical proof and pictures to go with it. Have fun.
