Need help! Is my understanding about the conversion mechanics correct?

Hello gorgeous people of Cairn! I would like to ask some questions bugging me because I’m still in doubt that I understand the conversion mechanics of this game. So please correct me if I’m wrong.

  1. For example I have a Physical Damage around 1000 and I use Righteous Fervor(Oathkeeper) as my default weapon attack and I have “Mythical SoulBlade” which has 145pdmg and 15% Physical converted to FireDamage and also has 100% Physical Damage converted to Fire Damage to Righteous Fervor using dual wield, does it mean that 200% of my 1000 physical damage will be added to my fire damage if I use Righteous Fervor as a default attack?

  2. Follow up question from number 1. If my number 1 question is correct then does adding more Physical Damage from Devotions/Augments/Components still benefit my fire damage since it converts Physical damage to Fire?

  3. If I have 5 items that converts 15% physical damage to fire damage, and 1 item that converts 15% piercing damage to fire damage, will the conversion prioritize the 5 items which has the MOST convertable damage and ignore the 1 item that has the least convertable damage?

Thank you!

I was just as confused as you are.

What was really helpful to me was korsar’s explanation: https://www.grimdawn.com/forums/showpost.php?p=631243&postcount=13

Okay, so from my understanding: If I have 50 physical damage, and 100% of it is converted to fire from an item, along with 100% of it being converted to aether from a skill, I will have 50 fire and 50 aether together?
But, if I have a transmutation for that 50 physical damage converts 100% it into acid damage, I will just have 50 acid damage?

Ok. I’m very pedantic about word choice, so forgive me if my explanation comes across as condescending.

I don’t like the word ‘it’ because it’s too unspecific.

But from what I’m understanding, you seem to be asking (and correct me if I’m wrong) - Assuming I have 50 physical damage, what happens to it if I have 100% phys/fire + 100% phys/aether conversion?

What happens is that these things enter a weighted pool very similar to how WPS works.

The game kinda goes…ok, this dude/dudette wants to convert a total of 100% of his physical damage into fire AND a 100% of phys into aether.

What I’m going to do is add these conversion values together - i.e. 100% + 100% = 200%. (Let’s call this my total conversion value)

Now…
(100% of physical --> Fire) / (200%) = 50% = 25 physical damage is converted into fire

Ditto for aether.

EDIT: To answer your edit…

What I mentioned above only happens for conversions occuring at the same ‘level’ of the conversion hierarchy (refer to the first link I posted).

If you have a transmutor which converts 100% phys to acid, and any physical damage dealt through that transmuted skill will be acid, and will remain UNAFFECTED by any other conversion occuring lower in this hierarchy.

Of course, the weighted converion mechanic will again apply if you have multiple ‘transmutor-level’ conversions occuring.

Let’s use this GT as an example - https://www.grimtools.com/calc/qNYxy17Z
50% of all physical damage dealt through righteous fervor will be converted to acid and another 50% to chaos

Btw, if you had an item convert 100% of X to Y and another item that converts 100% of Y to X. How does it work?

If you had 50 X and 10 Y, do you for example end up with 10 X and 50 Y ?

Yes. That’s exactly how it works.

Okay I think understand it completely now.
When total conversion value goes over 100%, all conversion types level out to take an equal amount of the damage being converted that is equal to the amount they convert.

So if I have 250 Physical, and my conversion types are 50% Fire, 100% Aether, 80% Chaos, and 20% Acid, that would equal 250%.

And out of that, I will end up with 50 fire, 100 Aether, 80 Chaos, and 20 Acid damage, equaling 250 damage. Correct?

Yes. But here’s a more general formula for it:

(flat value of damage type A) * [(X% of a-to-b conversion) / (%total conversion value)]

EDIT:

all conversion types level out to take a equal proportionate amount of the damage being converted that is equal proportional to the amount they convert total conversion value.

I’m confused by this. Aren’t those conversions occuring at different level of the conversion hierarchy? Shouldn’t it be 100% acid or 100% chaos?

The game guide states: The order of events for Conversion is as follows: Base Skill > Skill Modifiers > Conversion on the Skill or Transmuter > Conversion on Equipment and Buffs > Equipment, Auras and Passives

100% acid conversion (Dreeg’s reproach) is a transmuter, right? Chaos conversion (the one in the gloves) is “Conversion on Equipment and Buffs” or “Skill Modifiers”. I’m not sure which one. I’m assuming it’s a “skill modifier” since it modifies the skill directly and “Conversion on Equipment” would be those generic “x converted to y” things on gear. But either way, how is the damage converted 50/50 to chaos and acid in this case?

Read the links I posted up top… :eek:

Especially this one - https://www.grimdawn.com/forums/showpost.php?p=631243&postcount=13

to make this formula more general so that it works if %total < 100%
(flat value of damage type A) * [(X% of a-to-b conversion) / (MAX(100%, %total conversion value))]

I’m not that great with mathematical signs/coding language so I can’t comment :stuck_out_tongue:

But if it’s <100%, then it’s pretty straight forward since damage A will simply be converted by its listed amount.

yeah, such formulas usually make it harder to read :stuck_out_tongue:
but it does precisely what you said

if total >= 100% then MAX(total%, 100%) = total% and we get your formula

if total < 100% then MAX(total%, 100%) = 100% and we get
(flat value of damage type A) * [(X% of a-to-b conversion) / 100% = (flat value of damage type A) * [(X% of a-to-b conversion) / 1 = straightforward conversion

MAX is basically writing those ‘ifs’ in one line but in a less readable way

Gotcha. Then yes, that makes sense.

I would simply have added, ‘where %TCV is > 100%’ :stuck_out_tongue:

Well… fuck me. I did read them and looked at that picture too but somehow didn’t manage to connect the dots…

:stuck_out_tongue:

Not a problem mate. It’s really all very confusing. I just hesitated to answer because as they say - “a picture paints a thousand words”

Thank you for your help! It’s nice to have someone experienced answering questions.
