simple, instead of breaking it using a tentacle and also on the nether side, it should attempt to target nether portal blocks and break the frame to prevent players from escaping.

This would be hard to pull off since it would require scanning a large are of blocks, which in my experience would be very impactful on the performance. It would also be difficult to get the heads to line up with the trajectory of a skull to a portal. Thanks for your suggestion though.

Maybe not so hard to get it to detect the portal, considering its a POI so piglins can avoid it, but scanning it in a large area constantly would impact performance, so i understand why this isn't very feasible.

actually, what if it scanned the area near the player rather than near the storm, so it would only shoot if a player was attempting to enter and would require less scanning.

That could work, but it’d still be fairly performant intensive
