For example skill Zen with 2 seconds FCT.

 

Note: VCT -100% set up

 

1st Set up

 

Boots Temporal dex -0.5 sec

ME Enchant Level 7 -0.7 sec

 

FCT remaining 0.8 seconds

 

2nd Set up

 

Boots Temporal Dex -0.5 sec

+10 King of Spirit Set up -70% FCT

 

FCT remaining 0.45

 

Why is that using set up 1 cast faster Zen? Is king of Spirit Circlet working correctly at +10?

Short answer is that mixing -X% with -X seconds (flat time) is a bad idea. Something about it takes high priority with one and not other. Idk, someone smarter might explain it better but yeah. Same reason a -70% FCT (Fenrir) + Temp Dex .5 sec won't make a 1 sec skill be instant (think Acid Bomb).

wot? I can understand the part where it doesn't make a spell insta-cast because % reduction come after the .5 sec reduction and it is a % reduction of the remaining FCT.

 

Still, the 2nd set up should be faster than the 1st set up.

 

Edit: I'm saying this based on my understanding of the formulae and face value. If there's some other complex calculation involved then it's another case.

fixed cast priorities:

 

flat reduction first (-0.5 sec TBD/ME)

% reduction second (King Spirit/Secre)

 

====EQUALS

 

so yeah maybe some bug with King Spirit %fixed reduction

Nothing bugged with the circlet, you can't get instant cast if it doesn't remove it completely with either Flat or Percentage.

OP calculation are already correct on 2nd setup.

 

with zen having 2 seconds long FCT, combination of temp dex boots plus +10 spirit king circlet should give faster cast than first setup.

 

alternative way on how to test the accuracy of 70% fct cast given by the circlet is by comparing any mid / top fenrir carded headgears with temp boots setup on zen skill.

 

if fenrir and temp dex proved to be superior, then current +10 effect granted by the circlet are incorrectly provide fct reduction bonus.

 

another way to test it, apparently level 5 sacrament and temp dex boots still gain slightly upper hands, by giving zen 1,25 fct seconds cut (remaining fct 0.75 second)

 

if sacrament + temp dex boots are about the same/ slightly better than setup 1, then you can safely conclude circlet +10 fct reductions are bugged.

 

 

 

another sample of skills to test are mage class and its subtree energy coat, which requires 5 seconds fixed cast time.

In case OP want to notice more apparent differences between the 2 setup.

 

OP can make 3 setups scenario, instead of 2 setup where the setup are as follows :

Setup 1 (Magic Essence 7 + Temp Dex)

Setup 2 (+10 circlet and temp dex)

Setup 3 (sacrament + temp dex)

 

Expected Results (Hypothesis)

Setup 2 (1.35 seconds remainder fct) should by far beat setup 1 (3.8 seconds remainder fct) noticeably

 

Setup 2 (1.35 seconds remainder fct) is slightly superior than setup 3 (2.25 seconds fct remainder)

We know that

 

 

You did not answer the question. 

 

So why is ME enchant making it faster to cast than 70% FCT reduction. Even a ME level 5 will be a bit faster than 70% FCT.

 

Any secret your not telling us?

Same reason a -70% FCT (Fenrir) + Temp Dex .5 sec won't make a 1 sec skill be instant (think Acid Bomb).

 

The alleged formula (which proves wrong) is flat reduction first and than what remains will be reduced by the % mod.

 

So for a 2 second FCT with temporal dex boots its 2-0.5 = 1.5seconds and then if you are using the circlet this should be reduced by 70% which is 1.5sec - (1.5 x 0.7) = 0.45 seconds

 

While with Bio5 enchant magic essence for example level 7 with temporal dex boots which is -0.7sec and -0.5sec a 2 second cast should become 0.8sec which should be a lot slower

 

So obviously something is wrong here and Nirvana21 is silent about it. 

 

@Campitor

 

Hope you read this thread, something is not working properly in here its either one of the above is not right.

Here is the thing Cleofe.

 

The formula for FCT reduction hasn't changed.

 

The hat very much works.

 

Work the rest out for yourself. I am not here to tell you how it works.

So its the bio5 ME enchant that's not working properly obviously, you answered it.

 

Thanks!

dude, it's actually quite simple, FCT reduction does not add up.
so to get completely remove the fixed cast you have to get 100% reduction in % or numerical value "enchant ME to helm, Temp Dex".

if the reduction is mixed it would look more or less so.

Zen has 2s of Cast fixed, being removed 0.5s by Temp Dex, still have 1.5s left of cast, then would be removed the 70% of fixed cast of those 1.5s cast that remained.

 

I hope this answered your question.

2010 initial discussion reference on custom zen cast time for 1.43 seconds fct on zen

 

2013 balancing sura fct discussion to 2 seconds fct
 

another 2013 balancing sura fct discussion to 2 seconds fct

 

so let's hear official response from Camp or maybe Cinnamod can help enlighten us by bugging camp and wp crews to confirm whether the zen cast time stayed with custom 1.43 seconds fct or adopting official kRO 2 seconds fct.

EDIT: My clumsy stopwatch-in-one-hand test resulted in roughly 1.5s cast time for ZEN.  Goes to tell you how reliable information from iROWiki is...
