Well. I would love to see how does it works.
I tried to figure it out with Explosive Arrow due to it's high initial mana cost.

WITH NO MANA REDUCTION
Empirically:
Base Mana Cost: 18
1.4 Multi Mana Cost: 25
1.5 Multi Mana Cost: 27
1.4*1.5 Multi Mana Cost: 37

Calculations: (Base_Mana_Cost*Multiplayer1*Multiplayer2*...)
Base Mana Cost: 18
1.4 Multi Mana Cost: 25.2 -> 25 (round down)
1.5 Multi Mana Cost: 27
1.4*1.5 Multi Mana Cost: 37.8 -> (round down)

Wtf? Are Mana Cost's rounded down?! Always?


NOW WITH 5% MANA COST REDUCED
Empirically:
Base Mana Cost: 18
1.4 Multi Mana Cost: 24
1.5 Multi Mana Cost: 26
1.4*1.5 Multi Mana Cost: 36

Calculations:(Base_Mana_Cost*(1-Reduction)*Multiplayer1*Multiplayer2*...)
Base Mana Cost: 17.1 -> 18 (round up)
1.4 Multi Mana Cost: 23.94 -> 24 (round up)
1.5 Multi Mana Cost: 25.65 -> 26 (round up)
1.4*1.5 Multi Mana Cost: 35.91 -> 36 (round up)

And now it rounds up


So this theory fails. How does real theory look like?

10% MANA COST REDUCTION:
Base Mana Cost: 17
1.4 Multi Mana Cost: 23
1.5 Multi Mana Cost: 25
1.4*1.5 Multi Mana Cost: 34

Theory that seems to work, but look very... ugly is that reduction itself is calculated and rounded separately - and then Inital Mana Cost is reduced by it:

Inital Mana Cost: (Base_Mana_Cost*Multiplayer1*Multiplayer2*...)
Reduction: (Initial_Mana_Cost*(1-Reduction))
Resultant Mana Cost: Inital_Mana_Cost - Reduction

Inital Mana Cost: 18
Reduction: 0.9 -> 0 (round down)
Resultant Mana Cost: 18

Inital Mana Cost: 25
Reduction: 1.25 -> 1 (round down)
Resultant Mana Cost: 24

Inital Mana Cost: 27
Reduction: 1.35 -> 1 (round down)
Resultant Mana Cost: 26

Inital Mana Cost: 37
Reduction: 1.85 -> 1 (round down)
Resultant Mana Cost: 36

No. They do not.
It increases your base armor by 5%. It increases your base evasion by 5%. And then IR starts to work and changes this increased evasion to armor.

Example:
Base
Armor: 100
Evasion: 50

After 5% increase:
Armor: 105
Evasion: 52.5

After IR:
Armor: 157.5
I saw ppl using lighting damage or poison arrow. Choose freely.

Especially for you I'll try CI EA build. Then we will compare results (mainly skillcost issues), too check which build is more suitable for EA.

You can check out builds which I would use for now:

HP REGEN:

Rest of points can be used for either reses, fire damage, hp, hp regen, stat points - depends on needs.

CI:

I used much less points in this build, because I know nothing about mana issues in CI build. Probably I'll be forced to take many mana points. Rest of point can be used for reses (by mara), increased ES (in case of low ES), 2x endurance charges (since they are awesome) or more fire nodes

BTW:
You will have shitloads of life. With such amount of life I've never been stunned by last difficulty, so you don't need to take Unwavering Stance so early - stun chance strongly depends on hp pool. Secondly - even on last difficulty I was stunned only by rares with high damage modifiers, so I don't think you need US at all, especially u are ranged - I was melee.
