For abilities like Trick or Treat or attacks like Whatever a Spider Can, the wording "The target character suffers a collision as if the terrain were thrown into them" or "The enemy character suffers a collision as if the terrain feature had collided with it" are slightly vague in terms of execution.
Is there any operative difference in this and how an interaction with the target character would resolve had terrain actually been thrown into them? For instance, would Spider Sense allow dodge rerolls? Would Brace For Impact be allowed to be played here? I'm a little unsure how like a normal collision it is and isn't.
