[3.25] CWDT Ward Loop Scion

So I made my test by disabling my skellies and using GMP and Slower Projectiles support to see what's what.
Some weird stuff going on, I am telling you.

First off, a reminder that CP, like most projectile spell, doesn't fire sequentially, meaning even with 10 extra projectiles, only one will damage the boss. But unlike most projectile, CP explodes on contact with the ground so we can have every extra projectile deal AoE damage by having them explode at the boss's feet.

I've tested many simple things, but considering we're all using sniper mark, that's what I am going to discuss. Split was also the main reason I was so interested in Nimis Topaz Ring because it means one CP will split into 4, then come back for 4 AoE on target and then we have stuff like

So first, Nimis equipped, but no Mark.
The expected behavior is :
-No mark -> no split : YES !
-Random direction -> some projectiles will fly away : YES !
-Projectiles flying off -> will return at end of flight : NO !
For some reason, they don't come back (at least, not visibly). However, some creeping areas simply creep into existence without visible projectile as source.
So we have 5 projectiles doing area damage and occasionally, one of them fly off target and never return.

Now, let put the mark on and keep the ring.
The expected behavior is :
-Mark -> a projectile will split : YES !
-Random direction -> some projectiles will fly away : YES !
-Projectiles flying off -> will return at end of flight : YES ! NO !
As without the mark, projectiles that do not originate from a split don't come back. However, split projectiles do come back.
I do not imagine this is intended to work this way but what do I know.

So you might think, the mark still improve stuff, because one projectile turns into 4 and they all AoE the boss on the way back. Except not.
What we have is 4 projectiles flying off target (without the mark it was rare for even one to fly off) and not coming back, and one projectile splitting into 4 and coming back, doing area damage.
So, for some reason, the mark makes every extra projectile avoid the boss except for the one which split.

Might as well not use GMP right ? Except, while I have determined that the split projectile don't AoE on the way out, and that the GMP's extra projectile ignore the marked boss, evidence shows creeping area under the boss the moment the projectiles are created.
So, at least one projectile hit the ground.

I decided to remove GMP and use Divergent CP which fire an extra projectile.
The expected behavior based on previous tests is :
-One projectile splits into four, they all come back and AoE : YES !
-One extra projectile either land on the ground and create a creeping area, or ignore the boss, fly off and don't return. With a growing suspicion that extra projectiles flying off might somehow either AoE on the boss the moment they are created, like a frostblink spell, or that the creeping areas behavior is as obscure as teleported fireball with negative projectile speed.
YES ? Absolutely NOT !
What I got is just nonsense :
One projectile do split into four and they all come back.
What happens with the ONE extra projectile you ask ? I don't know. There are FOUR extra projectiles flying off into the wild because, why not. And of course, there is a creeping area under the boss, but I believe now it's created when a split projectile reach End of Flight and leave it's AoE at point of origin rather than EoF. I've been wondering why some EoF are without creeping frost and I assumed they were replaced because of the limit of 10 area but the hell I know.

What if, the one extra projectile from divergent quality is somehow different from a "normal" extra projectile ?
Well a normal CP with a Dying Sun flask reduced to one projectile by the power of Survival Secret behaves the same way as the divergent version.

What about Pierce ? I tested with and without, didn't see a difference.

Usage with Ice Spear ? In theory, it should double the damage because they are fired sequentially. In practice, ensuring they all land on the boss on the way back is unrealistic but I am not familiar with the width and precision of projectiles. I imagine if there is ever a support gem that give AoE to projectiles then yes it will be practical.

For now, I don't see how to use the Ring without reducing damage output on single target. Fury valve is one way to ensure every CP fired absolutely do land on the boss, but we're already doing that without the ring by simply staying near the boss.

And of course, I tried the ring on Simulacrum. At our loop speed, a barely understandable screen isn't something rare, but with that ring, it's something else, even with Frosbolt and Ice Spear projectiles coming back several meters above the character.

Perhaps I should just give up looking for fun but efficient way to looping with projectile and loop with Discharge or smt.
