how additional projectile work single target (shockburst round)

hi how additional projectile(scattershot- endless munition) work with skill like shockburst round, does if give extra dps ?

shock target activate a pulse(aoe) does the pulse shotgun the target

thx

Your shockburst rounds expands 1 bolt for per 2 bullet. If you have 20 when its full your total fire will deal 40 bolt damage (1 additional proj)

Don't add scatter shot anyways its a dps loss.

In general, skills that fire one projectile at a time will be limited to that many hits, so more projectiles would mean nothing when hitting a single target.
There are however shotgun skills that allow multiple hits, and usually come out of the gate with multiple projectiles.
For them, more projectiles are a way to scale single target damage, but scattershot is definitely not the way to go there.
Skills that create ground effects depend on the effect here:
Vines don't stack, but that shock arrow thingy does, and placed frostwalls may also detonate individually.

ok forget scattershot just with endless munition and shockburst round, do extra projectile double the dps since shockburst create a aoe pulse (single target)

because the game say extra projectile from the same source don't do extra damage?

A good ballpoint for guessing is that everything that comes out simultaneously deals damage once, while everything in succession deals damage repeatedly.
In this case, I'm not sure, because going by that logic, the first multishot would deal damage once, but triggering it with lightning arrows would deal damage repeatedly, as each chain comes after the other.
I didn't try that out much. Then again, the damage is abysmal just going by the initial hit damage...
