Hello esteemed creator,
I am not sure whether the opacity of the Glacier Entity for the Ice runic invocation is supposed to be fully non-transparent. For the small version of the projectile, it isn't that much of an impediment, but the large glacier obscures anything that is behind it. Sure, you can still target the enemy, but it makes it hard to focus on what you cannot actually see.

Would there be a possibility to increase the transparency of the projectile?

Example:

I have already checked for possible conflicts with resourcepacks, but this occurs in Vanilla too.
