Reduce Magika cost of spell glyph bug

Molsondry

Simply to say that Higer rank of reduce magika says they reduce for exemple by 200 for the kuta one. but in fact when you look at your stats its only reduce for 135 , wich is the normal white one. So the higer rank of this glyph doenst work its just a tooltip

Molsondry

Bump . anyone else noticed that?

Hookgrin

Not sure where you go to see that stat, are you using an add-on?

To test this I unequiped my Diamond Necklace of Reduce Spell Cost and popped several Blazing Shields. Then I equiped it and tried again. It was enchanted with a yellow glyph that I had made. The tool tip shows 200 cost reduction.

Cost of Blazing Shield:

without reduction: 3179
with reduction: 3017

A reduction of 162.

I'm not sure what other factors may go into determining the actual reduction, but then the tooltip should not say that it does 200 reduction, only that it can do "up to" 200.

No I just calculated my cost spell with and without the item equpied.

For emple my force pulse is 1261 magika cost in the tooltip. If I remove the ring it goes to 1395 in fact , according to tooltip, reducing it by 134. But my glyph is a kuta glyph and should reduce it By 200.

Wich is kinda big thinking 3x200 = 600
and 3x134= 402 . Its a 33 % effect thats missing right there.

But thats thinking all the tooltip are correct.

Edit other testing : Crystal fragment with ring 2073
without 2207

In fact again it reduce by 134. So its all the same patern . I get a 134 reduction from a 200 enchant. If the tooltip are correct.

Long time ago i had the same problem and thought its buggy. But its only a math problem.
You forget your passivs from light armour passiv, CP and maybe race passivs.

Its not 200 reduce on top.

Example:
A spell costs 1500 without any reductions.
Than you have 200 reduction from rings and 20% from passivs.
The 200 are on first position in math here.

1500 - 200 =1300 - 20%(260)= 1040 spell cost

And now without rings
1500 - 20%(300)= 1200 spell cost

So when you put out rings yes you can think you only get 160 reduction not 200.

OP is right. I noticed this a few days ago when I upgraded from a white glyph to a Kuta... and my spell costs actually went UP!

Needless to say, I was pretty unhappy at wasting 5000 G on a Kuta.

No, that's not what the OP is talking about. We all know about the "diminshing returns" effect of stacking cost reduction glyphs with other reductions from passives.

What's happening now is an outright BUG.

If it was the case . then Why would I have the exact same reduction on 2 different spell that cost different magika ressource. And we are talking double the resources.

V14 Magick cost reduction on a neck piece provides 188 Magicka reduction.
V14 Magick cost reduction on a ring provices 212 Magicka reduction.

V14 Stamina cost reduction both neck and rings provide 212 stamina (and dodge/break free) cost reduction for a total of 637.

I reported these bugs back in 1.6 PTS to no effect. I even mentioned the bug in a guild TS meeting with Eric Wroebel and @ZOS_JessicaFolsom to no effect.

The math behind cost reduction is rather complicated in 1.6 but if you want to calculate exactly how much your cost reduction enchants should be providing use the numbers I provided above as base reduction then add up all of your spell cost reduction percentages like Light Armor, Breton, Seducer, Archmage, Sorc Passive, etc then multiply *that* percentage by .8777 (don't ask why) then multiply that final percentage by the sum of the reduction enchants you're using and that is how much cost reduction they're giving you.

For example if you're using 2 VR 14 Magicka cost reduction ring enchants they provide 424 Magick cost reduction.
If you have full light armor, are a sorc and are using the Seducer set (21+5+8)= 34*.8777= 29.818% 424* .70182= 298 actual reduction to your spells.

Hope this helps.

@Molsondry

Ok I was able to reproduce the numbers you're getting.

You are a Sorc (-5%) wearing full Light Armor (-21%), Seducer(-8%), Archmage(-8%) for a total of 42% cost reduction. This gives your Magicka cost reduction enchants 134 per ring enchant.

Coincidentally if your base Crystal fragments with no spell cost reduction enchants is 2207 you have 5 points into the magician champion passive.

None of this is really bugged except the cost reduction by the magicka neck is lower than the rings and the tooltips say 200 when in fact they're providing between 211 and 212. (623 for all 3 magicka).
