idk man
I have rewatched this several times and I think the most obvious anwser is a boss destroyed it by spawning in, but it happened a couple seconds after the fight proper started, so that seems to be out.
Then I guessed he destroyed them with the attack, but then I am not sure because of how.. wonky the attack was?
1)It hit a couple minons and the mage that is right in front of me. OK fair enough. But then..
2) It somehow hit like 3 towers waaaay further back, also taking down the beam by proxy. Which is really odd, because:
3) It didnt hit me, and I am closer to him, and then it ALSO didnt destroy the lone fireball tower that happened to be the closest to boss out of the tower cluster
I just dont know man. I am missing something?
