Barrage the CoC gem: theorycraft and ST comparison

First let's see its effective attack mod:
assume 100 damage with 1.00 weapon for 100 dps
What barrage does
-rather then 100 each hit will do 40 damage
-attack time will be changed to 0,67 attackes per second
-each attack will fire additional 3 projectiles so
40x0.67x4 = 107,2 dps what can easily mean a drop in dps considering armor.

So its purely a CoC attack for bows and wands. Comparing it with ST:
With ST per attack you get 2 triggers , possibly 3 with knockback/big targets.
Barrage does 4 hits but it's 33% less attack speed so it does 2,68 triggers if you would scale it back to one attack time


What however set those apart is interaction with supports. Since you do not care for attacks damage itself you can link GMP easily. For barrage it will double the amount of triggers on signle target while for ST it won't do anything. On the other hand GMP with ST gives great amount of triggers for multiple targets while for barrage it won't matter if its one or 100 mobs on screen.
However adding supports like Fork and Chain each will double the possible amount of triggers for barrage in aoe scenerio. If you would do that you most probably want to use non-projectile spell with it so its damage is not reduced to ground.

Hard to tell which is better. It's quite possible dagger CoC will want to swap to wand for bosses. Whatever it will work the other way - hard to tell.

IF you could face tank then for boss Barrage+GMP+CoC+spark+supports i think would get best results. For aoe its either get trigger mult supports and FS/SC or chain+EK.


critical strike chance dagger vs wand

Wands get 2,3% more base weapon crit chance. There are however no wand specific crit passives. To even that out for:
X -increased critical chance
TO get same crit % chance on attack with daggers as wands you need Y extra crit chance with daggers :
Y=2,3*X/10
On average 150-200% crit with dagger satisfies your needs. You get 190% dagger crit chance in 3 NE clusters.
(not mentioning implicit since wand spell damage even it out)


AoE scenerio : hit count

All numbers are scaled to 1s with 1.00 attack per second weapon.

Barrage:
GMP= 5,36 hits
GMP+chain=16,08 hits
Those are two most probable and then you can swap chain for faster attacks when facing boss.

ST:
2-3 hits per target regardless of supports.
Just 2 targets should be enough to generate 5 hits if you aim well.
7 targets easily generate 16 hits and you use 1 support less.

Spell synergy:
For aoe spells there is no differance.
==>Spells that work better with ST - ice spear,Fireball since with ST you can just use LMP and lose less damage on them.
==>spells that work better with barrage:
-Arc- arc won't lose damage from GMP even if you link it and will benefit from chain if you decide to use it. Good for small packs but lacking for big ones.
-EK-This one will work best , just stick to fork/chain and not GMP/LMP




Single target

Barrage is same as previously:
GMP - 5,36 hits

ST- 2 hits with possible 3 hits with good aim / large target. 0 supports

Supported spells:
===>Barrage:
-Spark is the best option if you can keep close ,Shotgun attempt with Freezing pulse/Fireball is possible but probably not worth it
-Arc - to keep distance or alternative Icelance/ Fireball but without GMP
====>ST:
-Fireball / Icespear
-Arc against mobile targets


What's better?

Barrage will offer up to ~3.5 times the dps on single target dps if you can facetank and ~1.5 times if you need to kite.
For small mob groups (5-8) they are about even and against big packs ST will do better the bigger they are - hard to put number here let's say 3 time?
Overally barrage is better CoC skill since this build type struggle with single targets and barrage is covering for that.

Does it work on a ranged totem? Give that a try.
It didn't work with Frenzy ealier so no reason for barrage to work. CoC doesn't get inherited by devices/minions what kinda makes sense.
I did try it however, to be sure and it doesn't work
It is still a pretty fun skill when put on a Quill Rain. Like a machine gun :)

Quill Rain + Freezing Pulse is the best way to go with this IMO, due to Quill Rain's faster projectiles narrowing the shots and increasing FP's range.

The only problem is you're strapped for links after Barrage+CoC+Freezing Pulse+GMP+Life Leech. Lots of good choices at the 6th slot including:

1. Faster Attacks
2. Cold Penetration
3. Crit Multiplier
4. Blood Magic

And since you're using Voll's, you can't get 6 links easily with Tabula Rasa.

I think the Blood Magic keystone is a must-have with this build... And so is Vaal Pact (so Devouring Totem CwDT).

This is the build I have planned.
Wouldn't berek's grip work as a substitute for the leech gem if you go FP?

You could always go faster proj (more for damage than anything, as your FP will be hitting off the screen already) or high quality culling strike (pure damage).

Or add a second FP
I found that Cyclone was the most effective skill to proc CoC vs spectral throw or frenzy. Also linking exta skills with CoC (e.g. Discharge-Discharge-CoC) is almost always better than support gems.

The more of those you have, the more you die to reflects (or atleast bigger chances of death).
