Can Bard's tunnel go through impassable objects? I.e. J4's cataclysm, Anivia's wall, Azir's ult, etc

He can't portal on those abilities but he CAN get a Q-stun on them. But yeah, his E has no interactions with any player-made terrain unfortunately. I've had a bunch of times where It would've been really cool if I could do that. Like imagine you and an allied Anivia chasing someone so she walls sideways and you portal through it.

idk nice question

I've tried casting Magical Journey on walls created by spells, but it seems like it just goes straight through these abilities and will hit a terrain wall if one is nearby. Also, Cosmic Binding (Q) WILL interact with player-made walls, so feel free to take advantage of that!
