Level based FX on Skills

Hey,

there is this note in the patch notes

Updates to many projectile, impact and AOE spell FX

I’ve seen the “new” Olexas Flashfreeze on MrTek twitch channel and I was hyped to try out the new FX.
I started with lvl 3 OFF and there was nothing special prior the patch, same as lvl 6 OFF.
Then I leveled to 9 and… wow one amazing change. It looks so cool. So I didn’t tried out on which level the new FX starts.

So my question is, because there are so many new visual effects on know skills, are there any other skills that reveals their beauty at a certain level?

Thx

I’d like to know that too
