As the above poster mentioned, don't stack everything into Spell Cost Reduction. Another reason for this is because those types of modifiers ONLY apply when actually using an ability. Sure ideally you'd be using 1 ability per cooldown but things happen and Magicka Recovery overall is better as it will continue regardless of ability use. Passives like Breton racial are great for this but I do not recommend using other forms i.e. Jewelry enchants etc

it isnt worth to put everything to cost reduction because more you have, less you get. you can see it by yourself. equip one cost reduction and look on skill. then do it again and again.

i play mostly nocp pvp - i have 2x infused cost reduction and one arcane recovery and it suits me just well

Max spell reduction in the game-

Infused cost reduction jewelry- 324 x 3 = 972

Light armor passives-14%

Seducers- 10%

Alteration mastery- 6%

Worm- 4%

Then there are the specific cost reduction-

Eyes of mara- 15% cost reduction of resto skills.

Master destro, 30% cost reduction to destructive touch skill



There are more but don't have time right now.

Worth noting that those percentages are multiplicative, not additive. So, you'll experience diminishing returns as you stack 'em up.

So, the LA passive will take your cost down to 86%, but then your Seducers will only reduce that by 8.6% to 77.4% (not 76%), then your alteration mastery will only reduce that by 4.6% to 72.8% Worm will only give you another 2.9% on that, bringing it down to 69.85%.

Pretty sure this is wrong, here is the formula that @Masel has in his damage dealer thread-

Skill Cost = (Base Cost * (1 - CP Cost Reduction) - Flat Cost Reduction)*(1 - % - Cost Reduction)

Now of course, even if the cost reduction percentages were additive with each other, there simply isn't enough to make skills cost nothing, since the flat cost reduction glyphs are first.

Though reading that section, @Masel, it seems to be a bit out of date now. Wonder if it is.

It was changed a few months ago (Scalebreaker maybe?) from additive to multiplicative. It was the same time they increased Worm from 4% to 5% and Seducer from 8% to 10%. Effectively it was a nerf to Light and Medium Armor, Breton/Redguard/Imperial races, and False Gods/VO sets.

Yeah, changed with either Scalebreaker or Elsweyr, I forget which.

To be honest, it was always a little weird, because there were specific interactions that were always multiplicative, even back then. The specific combo I remember was Dragonguard and Power Stone (from the Sorc) were multiplicative. (Adding them together would get you a 27% cost discount, instead of 30%.)
