Glyph of Reduce Spell Cost provides less than it says

Mystrius_Archaion

I just made some Truly Super Glyph of Reduce Spell Cost and decided to check how it affected my skills. It says reduces their cost by 191, but, with only one enchant of this type slotted, it actually changes the cost by only 183.
That is clearly not matching the enchant value. This is not just a text error as I believe the 191 is the intended value, but the actual value needs a fix.

I am not sure if this affects the other levels of this enchantment yet, such as legendary quality, but I would not be surprised.
I wonder how long this has been bugged this way?

Please fix this ASAP.

Hopefully it's a bug. More likely its some weird calculation rules going off some odd base number or something!! Like dem damn tooltips

Are you Breton maybe? Or having any light armor equipped when trying it? Because it reduces the base cost of spell, before further reductions from passives. So you are essentially getting less from those than you did before (10% of 100 is less than 10% of 90)

Not Breton, but was on Templar with the 4%(pitiful honestly) cost reduction from passives.

BUT
That enchantment is not a percentage. It's a flat number reduction to the cost of the skill. It should not be affected by any percentage cost reduction changes to the skills themselves. Also, it affects all skills equally. I would prefer if it were a percentage sometimes though as it would be a larger effect on my more expensive skills.

I tested this looking at Purifying Light, which is very cheap, and Radiant Glory, which si very expensive. The decrease in cost was the same, both not matching the tooltip.

This enchantment must be bugged.

it's not bugged, like said sodantok the cost reduction is applied 1st, then % réduction.

for exemple:
we apply un cost reduction of 10% (or 4%...nvm)

skill A= 1000 magicka
skill B= 2000 magicka
skill C = 3428

without glyph:

skill A : 1000*0.9 = 900 effective cost
skill B : 2000*0.9= 1800
skill C: 3428*0.9= 3085

with glyph 191 cost reduction

skill A: (1000-191)*0.9=728 you save 172 magicka
skill B: (1000-191)*0.9= 1628 you save 172 magicka
skill C: (3428-191)*0.9= 2913 again 172 magicka

with 4%
Skill A : 960
with glyph : 777, you have your 183 cost reduction



that's why regen glyph look not that good, but are in most of case are better than cost reduction. because the math are

glyph tootip * (race passive + vampire passive + potion passive etc...)

TLDR: or if your not good at the math

original value less flat value less percentage value

It's not. But the final cost of the skill is.

Let's say you have a skill that costs 1000 magicka. You have a glyph that reduces cost by flat 500. Result: your skill will cost 500 (1000-500).

BUT.

Let's say you also have light armor that reduces skill cost by 50%. You have this, but not the glyph. Skill cost is 500(1000 - 50%)

Now you equip the glyph. The cost of the skill will be reduced to 500 cost by the glyph. And then the result (500 cost) will be reduced by 50% by the armor. 500 - 50% = 250.

Wearing light armor, your cost goes from 500 before equipping glyph, to 250 after equipping glyph. This is your wtf moment: why does a 500 reduction glyph only reduce my cost by 250? (because of the above)

Ok, so I have to test this next time I respec my skill points, which will be soon.

This is yet another example of the developers not letting us see how things work well enough to figure it out and not post flawed bug reports.
I really really really miss City of Heroes where they let us have an official sanctioned stat tracker they built into their game for us to play with theory-crafting on our characters. I loved being able to see in real time how much my stats like healing per second changed with number of enemies around and other fun stuff.

Thank you for pointing out the flaw in my calculations everyone. I still have a bit to learn about the hidden numbers of this game, and sometimes miss the obvious.
I tested after a complete skill reset and the glyph is 100% accurate.

This makes my decision of whether to go with reduced cost or magicka recovery more difficult, which is a good thing. I'm probably leaning towards recovery which gets buffed more by skills.
