2) Jade Crystal Labyrinth: Sure, I can have a set up time. I'd say... Two post for the large massive version, but smaller versions will be quicker.
3) Protective Crystal Dome: I based it off the protective Ice Dome Haku uses. It's pretty much copied word for word.
4) Demonic Mirroring Crystals: This is also based off the canon ice jutsu used by Haku. Ban this and you pretty much ban it for all ice users. It has the same limits that it does.
5) Blossoming Fruit: Sure, the weakness is that it's senbon, so they actually have to pierce your defense.
