Reduced mana cost of skills on rings does not work with the new life mastery.

Hey. There is an unveil that is hybrid mana + % reduced mana cost of skills on rings which does not reduce the mana cost at all.

The item:

I'm running two of these rings and only the flat reduce is calculated on the skills.

show the math how it does not work......


also, reservation is reservation , cost is cost .....and increase and reduce modifier are additive together first, and the use the final sum to multiply the cost

No one is talking about reserve. You are right it does work normally but I actually found the bug causing it in my scenario.


My 6 link TR cost total 41 mana.


I use 2 rings one ring has -7 flat other has -6 flat
These 2 rings has 6% and 7% reduced mana cost of skills

According to the game (41 x 0.87) - 13 = 22,67 and indeed in game I have 22 mana cost

However If I use the new life mastery "skills cost life instead of 30% of mana". What this does is splits your 100% mana cost into 70% mana 30% life cost.


At the end with the same rings and total 41 TR mana cost it transfers into: 15 mana and 12 life cost.

I think this is where the ring stops working. Do the new math:

(41 x 0.7) - 13 = 15.7 and in game I have 15 mana cost + 12 life cost. Seems fine BUT where is the 13% reduced mana cost of skills from the 2 rings then?

The way it should work is: ((41 x 0.7) x 0.87) - 13 = 11.979 so my mana cost should be 12.

I do still have mana cost so it should at least work with the mana portion but it does not.

public this and post screenshot that show your final mana and life cost......



Also flat increase decrease cost calculate first and then the increase/reduce mod i think.....(just like res and damage)

Flat reduction comes last in the equation.


picture of my TR cost with the life mastery and 2 rings I just showed in the topic:


Ok just to do a quick explanation.

41 = total cost
0.7 multiplier is the 70% mana split (life mastery)
0.87 multiplier is the 13% reduced mana cost of skills on my rings (6%+7%)

-13 is the flat mana from the 2 rings (6+7) bench craft

equation:

41 x 0.7 = 28.7 (this is the mana portion 70%)
28.7 x 0.87 = 24.969 (this is the 13% reduced mana cost from 2 rings)
24.969 - 13 = 11.969 (this is the 13 flat mana deduction from the 2 rings)

end cost should be 12 mana 12 life not 15 mana 12 life.

Last time I've seen this issue was raised, people concluded that "- X to Total Mana Cost" stats are affected by 0.7 multiplier thanks to this mastery. Likely unintended but there might a technical explanation to this.

This is not the case because of this:

The life mastery splits to 30-70% right? So that means 41 total mana cost x 0.3 = 12.3. If the flat also split then why is my life cost 12? It should be lower than that then.

One way to get to the bottom of this is, do you have 2 other rings that don't have that unveil that you can craft -13 total cost to? If you put those on, is your cost still 15/12? That would tell us for sure if the 13% is working or not.

Sadly I do not have but perhaps someone do who can just put on that mastery node and tell us the cost.

I'm having the same issue. POB is showing my final mana cost as being 5 lower than in game. They are both calculating it differently. Bummed because 7 mana vs 12 is pretty big in my case
