found some completely useless tech
when you ult destructible terrain, and it breaks, the ult doesn't vanish, it just falls straight down from where it is. If someone is stuck to the ult and they also fall, they can stay tied to the ult on the way (if they're separated too far the ribbon snaps as usual)
the only possible application i can think of is if you could somehow use the destructible terrain to exploit the earthbound part of the ult, like somehow some building breaking might move the victim closer to a pit. But then there's the issue of tenacity ending the earthbound early so idk
it looks cool though, seeing the spear fall
