Cospri CoC question: Impossible to maximize DPS potential?

Okay, so... This is going to be for the Cospri VETS.

I've been plagued with the realization that I'm not actually utilizing Vortex's "casts on up to 5 Frostbolts" potential.



The TLDR Question:

Is it impossible to?



Elaboration of the question:

When a single cast or trigger of Vortex (of Projection) is popping balloons (casting on Frostbolts and consuming each Frostbolt when it does so), it has a little bit of a delay between each balloon pop. This means that, after one or two balloon pops, the remaining Bolts are long past the target, and the remaining Vortex repeats won't even hit your target (in a stationary situation).

So with this problem, my thoughts are... how do we get these Bolt projectiles to still be in the area?

Well... Slower Projectiles Support isn't potent enough. The Bolts are still long gone too quickly.

Then I saw Gluttony Support, or whatever it's called. Wow! Projectiles go in a circle?? That should do it! Oh, wait... I can't use that with triggered spells. And I'm not seeing any other source of making my Bolts move in a circle...

And as for Return, I'm pretty sure the Bolts still have to go out way too far first, before they return.

Additionally... there is another blockage in the road, and that's the socket limit of the Cospri. Saying it out loud, I suppose I could look into the Squire shield, but as I was going to say: Cospri proc has a 0.25 cooldown, while CoC has a 0.15 cooldown. Because of this difference, even though your first hit might trigger both Frostbolt and Vortex, your subsequent Cyclone hits are going to be lopsided/unsynced with the cooldowns. You get more Vortex procs than you do Bolt procs. And if EACH Vortex proc needs 5 Bolts for maximum utilization of their effect text, you'll need maybe... 10 Bolts per Cospri proc (not quite 10, but the logic is that you'll need to accommodate).



SO MY QUESTION IS... have we the Cospri community accepted that it's impossible to fully utilize Vortex's effect text of popping 5 balloons per cast? Because NOBODY talks about any of this, and NO BUILDS have this solved, or even attempted or addressed it.

No Cospri veterans anymore? Everyone jump ship?
As an update, I've had some adventures:

If I spend 8 points to go deep southeast in the tree, I can get 20% reduced proj speed and 15% less proj speed. Combining this with Slower Projectiles Support, I CAN get the Frostbolts slow enough to where all 5 Vortexes are basically in the same spot. (This is with Squire, as I still need 2 support slots for ~10 projectiles.)

However, if I don't do Squire (and go back to Malachai's Loop) and just use the 8 tree points, I can pretty reasonably make sure 3 Vortexes are still hitting a stationary target, maybe even 4??? if they're big enough. And that ends up being better for me, with my build setup. But stacking ALL of that slowed projectile stat is an option, for making 5x Vortexes happen in the same spot.

:)




Still weird that nobody talks about this, though. With normal projectile speed, you're lucky to have a single Vortex trigger hit your target twice, let alone up to five times.
I would guess it's not possible not that it hasn't been a hot min from the last time I played coc frostbolts. The cooldown of coc is heavily nerfed from back in the day so it probably functioned better in the past. Returning Projectiles gem might be your best bet for getting more frostbolts to blow up I would think. Possibly try it without slower projectiles also it might turn out to work better if they return faster.

Anyhow good luck it's a fun build even if not 100% effective.

Thanks for the reply!

Well, returning the projectiles doesn't work out, because Frostbolt has to travel its entire set distance before it returns (which is far). The Vortexes already eat them up before they even begin to return.

I do think maximizing the slow projectile speed is the only way. (If we had a good source of making the projectiles spiral around us, THAT would be the best, but I don't think we have that in the game right now.)

Since that requires Squire for me to maximize the reduced speed, that means no Malachai's Loop, which is not only a huge damage-per-Vortex nerf, but it's also a huge Energy Shield nerf. I could probably EVENTUALLY make up for that ES loss by maximizing my helmet and glove slots, but as you can see from my char, those slots are already insanely strong, and it would be super expensive to self-craft better ones with Energy Shield values. (But that's still probably my next goal! Always good to have goals, this char feels nearly completed anyway.) The damage loss per Vortex is probably made up for by making sure all 5 Vortexes hit per trigger, but with Malachai's Loop, I only need ~3 to hit to basically be the same DPS (or slightly better). But I do admit, in most situations, probably only 2 Vortexes are hitting right now.

It's a min/max in either case, but it's a min/max I've been obsessing over, lol.
