Weapon:
Quill Rain Short Bow
+(10-20) to Dexterity

The damage of the explosion is considered projectile damage, but not weapon damage.

523-785 fire damage per charge * 5 charges = 3270 avg base fire damage per explosion

optinal
http://en.pathofexilewiki.com/wiki/Concentrated_Effect
66% MORE EoA damage
30% Reduced Area of Effect radius

+/-200% increased elemental damage / fire damage / projectile damage /AoE from gear+passives

Damage becomes
3270*3increased damage*1.66 More Damage = 16284 explosion damage at 5*Fuse

Attack speed for bow:
base weapon speed * ((100%+%weapon attack speed)/100) * ((100%+%attack speed from passives and offweapon gear and support gems)/100) = Attacks per second
1.55 * 2 * ((43passives+40gear+44faster attacks support+14hast aura)/100) = 7.471 aps
1/7.471 = 0.13385 sec per attack
5Fuse*0.13385 sec = 0.7seconds needed to get 5 Fuse up!

16284 damage per explosion / 0.7sec needed for the damage = 23262 Damage per second
23262 effective dps when aim perfectly between 2 taregtes just in 0.7sec
16284 /1.7sec between 2 explosions when fighting 1 singler target = 9.6k dps vs single target, excl the 1sec per 1.7sec of shooting whit a other skill!
23262 effective dps when shooting errows in a tree/wall and monsters are nearbye
<40 dps onscrean

Pretty cool in concept, at least. Would love to see how well it works in practice.

Theorycraft away, Tommy. It doesn't have to be the best, as long as it's different.

is this char built already? or just planning?
theres a guy on my friends list that uses similar build
is it you?! ^^

A lot of people already running this build (Me included) LMP works wonders when combined with EA. I found that only single target EA was taking too long to kill packs, it's a lot faster with LMP, haven't tried with GMP but I don't think I will it seems like there would be too many wasted arrows with GMP.

no its not me!

i am planning a Quill Rain Short Bow guide for over a week now,
and Explosive_Arrow is great for it
Elemental hit not brings me above 3k, since it gets a -50%weapon damage
Other skill are not based on skill damage, more on weapon damage/gear damage

Fork/chain/LMP/GMP only makes it harder to time the detonation wright
i am talking, after 5 shots on 1 target, you want to prevent other shots from hitting it, so it can detonate in 1 sec
it would allow a multiple detonation, but will force you to stop shoot 1sec per 1.7sec
so keeping it simple and use 1 projectile per shot is fun+ez+allow to keep shooting+gives room for usefull gems

already testing it on a lvl48 char of me, a lvl1Explosive_Arrow +ias support+loh
its way underleveled, and still powing good!

Ias support is kind of a wasted support especially when using Quill Rain. You're better off using Chance to Ignite, or Elemental Proliferation, or Life on Hit (Due to Blood Magic)

seen it a lot, especially maras running it.

Different and efficient.
