Perfect Half-Remembered Goliaths dysfunctional with Spell Echo

Hello, using a very fun and built-up-from-scratch Perfect Half-Remembered Goliath build.

However, with Spell Echo it appears that the spinning beam move (which is prefaced by them shooting out a handful of lightning balls) does not collide properly with the balls. It may ultimately be the balls themselves, as they also appear to be intangible with regards to enemies.

There are some other threads on this issue.

Either way, this makes it incredibly clunky from time to time. I have 5 of these guys as my main damage, and they also do not pop each other's lightning balls.

Here is a quick video from a few days ago:

You will find that from 0:27 onwards, a handful of those minions have their beam sweep echo'd but pop 0 balls. The beam also has a weird perpendicular angle to their arm, and it appears to only be their left beam.

This is the primary cause of any remaining balls, since they seem to only summon the balls to clear them with the beam. Therefore, if there are any left on the screen, they're probably intangible.
