Shuriken Charge on Frozen Enemy

I've definitely hit enemies frozen by Ice Spear / Ice Mine while fully charged, as opposed to uncharged which is what it currently says. However, sometimes I miss out of the blue, sometimes I hit; it's a really weird thing.

Is it possible that loading charge before or after the enemy gets frozen have something to do with that?

It might be a glitch or something. It can hit other unhittable enemies as well such as when red dragon is using meteor and lightning nothing else can really attack it then, and even glitched monsters that can't be hit by anything like a glitched sasquatch or ifrit. You can hit them without charging at all in the case of glitched ifrits.

I guess I haven't tested fully charged, but I've noticed my half-charges haven't been working so I just assumed fully didn't. Will have to play with it some more, and maybe amend that it can hit invincible enemies or something.

It doesn't hit enemies in their invulnerability frames though, like Smash, Crisis, Monster Life Drain, etc.

Scratch everything I said, after further investigating it seems uncharged hits all of the above rather than fully charged. I think I must have gotten it mixed up with something else x.x
