Optimal Blood Oath for mixed Demon builds

After reading Pavke's post (and other "features" like indestructible eth weapons):

He says Blood Oath does not give res or life bonsues in this post. He also gives this nugget:

"Not only does Cursed Demon Amp Damage apply at full effectiveness against Physical Immune monsters, it applies twice if you have a physical Sunder charm!"


...lol... and this one

"You only need to have Sunder charm in your inventory when you start the game in order for this bug to apply on your Cursed Demon. Because Bound Demon is “resummoned” on every game startup. Demon inherits physical sunder effects from your character. After starting the game, you can swap out Sunder charm if you don’t need it. Cursed Demon Amp Damage will still apply twice vs Physical Immune monsters. "

We tested that after seeing that summoning a Tainted with a flame sunder and then putting the sunder back in the stash resulted in Tainted that still had the sunder effect.

So I've been starting every game with a Bone Break and inventory full of skillers then swapping them out.

What I really wish I knew is how the bound demon damage gets calculated.

E.g., base damage of demon = 100, Bind Demon flat damage = 100, Bind Demon enhanced damage = 100%, Aura damage = 100% (keep it real simple)

Is the calculation:
Damage = (base damage[100] + flat damage[100] + (base damage[100] * EnhDam[100%])) + Aura[100%] = 600

OR

Damage = ((base damage[100] + flat damage[100]) + ((base damage[100] + flat damage[100]) * EnhDam[100%])) + Aura[100%] = 800

OR

Damage = (base damage[100] + (flat damage[100] + (flat damage[100] * EnhDam[100%]))) + Aura[100%] = 600

OR

Damage = (base damage[100] + flat damage[100]) + ((base damage[100] + flat damage[100]) * (EnhDam[100%] + Aura[100%])) = 800

Maybe I'm missing other ways of slicing up the numbers...


What would also be really cool is understanding how their affixes work. For example, Spectral Hit adds 66-100% of physical damage dealt as any of Fire/Cold/Lightning/Poison/Magic. Is that 66-100% calculated from the bound demon's base damage (100 in example above)? Base damage + flat damage? Base damage + flat damage + enhanced damage? Base + flat + Enhanced + aura???
