Can something cause/prevent stygian spire spawn?

Edit: I did get my spires. At this point, I'm thinking I may have thought it a bit too far, but I'd still be interested hearing, if there is an easy/optimal way to do it. I think I eventually just relied on pure rng and none of the nonsense I was thinking didn't really matter.

Hello

I am trying to completel the challenges for this league. One of them requires me to destroy 5 stygian spires. I ran out of scarabs that I can use to force their spawn (or to my understanding low chance of abyssal depths).

To my understanding they spawn on fourth pit, so I took up to Trail of Destruction in atlas tree. I also have the part of the one lower that says, if abyssal depths doesnt spawn, it will give chance spawn a stygian spire instead.

The wording of stuff is weird here.

Trail of Destruction says abysses that dont lead to the abyssal depths will spawn a stygian spire, if it can. What is this??? With this passive taken, my abysses do indeed go up to four pits, but I have yet to see a spire, but I have seen abyssal depths.

I will admit, I might be mistaken here since I started to shuffle about the passives. I tried googling, but all I find is the thing people did last league. If there is information there, I cant find it.

I did notice in some image that was not discussed that the trail of destruction was not selected? Does it cause the spire not spawn?


The way I understand the wordings here is that this setup will always give me 4 pits regardless whether abyssal depths will spawn or not. In other words, each time it does not spawn, I should have a chance of spawning a spire. Is the spire more rare than abyssal depths?

I would say use the abyss all-flames. They have spires everytime and a lot easier to just throw and go.
