Fine, let me break it down for you while using whirlwind in the second skill slot on a sunken sword as the example
The cost of whirlwind:
The level of a sunken sword:
So the formula to have whirlwind in the second skill slot of a sunken sword would look like this:
So if you follow PEMDAS, in this scenario you would
start by multiply 50 X 2 to make 100, and at this point, it
wouldn’t matter what you added or subtracted first, basically making
the stat requirement 100 to whirlwind on the second skill slot of a sunken sword since
30-30 makes 0. What’s left behind when the cost of a skill is 30 is just the weapon level x 2 since 30 is subtracted from the formula. The
30 extra points you’re talking about in your first comment is just the cost of using tempest on a weapon before going through any calculations
Seemingly, the formula used doesn’t work for weapons under level 50
For example, using the formula to calculate the requirement to use whirlwind in the first skill slot on a Ravenna or Keraxe sword (both are level 20 weapons) should equal 40 when the requirement is 60. Basically the Ravenna and Keraxe swords are 10 levels off. If they were level 30, the formula would work. My best guess for this discrepancy is either a different formula is being applied or the devs manually inputting the weapon requirements.
The formula also doesn’t work for old weapons, since all of the old weapons are level 1 and the first skill requires 20 weapons. There’s clearly a different method being applied. It’s likely that 10 is just being subtracted from the skill cost since they’re just starter weapons.
For hybrid weapons, the stat requirement is evenly split between 2 stats, which is why the entire formula is divided by 2, making tempest, something that would normally cost 200 weapons on a normal weapon, cost only 100 weapons and 100 in another stat. The point of this topic is to discuss how stat requirement will be handled in cases where 3 or more stats are required to use a weapon skill. I came up with Method A which divides the requirement by the amount of different stats required to use the weapon skill, and Method B which divides the entire formula in half for each different stat required.
I realized I made a mistake with wording my first reply. I meant to say that the when the skill cost is 30, the formula cancels out the added skill cost since it subtracts 30, which leaves the weapon level x 2 to determine how much of a stat is required to use the skill on a weapon. Other than that, I’m pretty the formula is how the stat requirement for weapons are determined. To deal with hybrid weapons that use 2 different stats, dividing the initial formula by 2 is likely how the stat requirements are determined. When it comes to hybrid weapons that require 3 or more stats to use a skill, I came up with 2 different methods by changing to formula to accommodate
