First batch of Crystal Release jutsu

Name: Crystal Tomb
Rank:S
Type: Ninjutsu
Element: Crystal
Range: Touch
Description: The user touches his opponent and implants a small crystal into their skin. The user then multiplies it in an instant, encasing their opponent in a crystal prision fit directly to the opponent. It can be broken by other S rank techniques, or 100 strength from the outside. It takes 120 strength to break from the inside. The opponent is alive inside and uninjured, although they are completely restrained.
Requirements: Learn from Ha

Name: Crystal Armor
Rank: S
Type: Ninjutsu
Element: Crystal
Range: Close-Ranged
Description: The user constructs brittle crystal armor that would break if hit by 100 strength, but would shatter and leave the user uninjured. The user can choose which body parts to armor, but it would cost the same no matter how much the user would do. It’s immensely light as well, making it easier to run around in.
Requirements: Learn from Ha



Name: Crystal Wonderland
Rank: S
Type: Ninjutsu
Element: Crystal
Range: 50m Diameter
Description: The user puts his hand on the ground and turns the ground in a large area around them to crystal. Any person who isn’t the user that steps on this crystal has their feet encased in crystal, and every time they break it, it’ll reform upon their feet. If the user of the jutsu wishes to, they can force the crystal up to opponents knees, but that’s as far as one can go. It takes 100 strength to break out of it.
Requirements:Learn from Ha

Name: Crystal Iron Maiden
Rank: S
Type: Ninjutsu
Element: Crystal
Range: Melee
Description: The user creates a coffin around the opponent at a high speed, and if the opponent is caught in it, they coffin lid will shut. The user then creates spikes on the inside to impale the opponent repeatedly. The size of the coffin is completely dependent on the opponent. The spikes strike as if at 100 strength. The Iron Maiden is also at 100 durability.
Requirements:Learn from Ha

Name: Bijuu Restraint Technique
Rank: S
Type: Ninjutsu
Element: Crystal
Range: 50m
Description: The user puts their hands to the ground and starts to create crystals. The user then sends those crystals up out of the ground in thin, rope-sized bands made to be hyper-dense. The user then starts to wrap the crystal around the bijuus body and limbs to attempt to restrain the bijuu. If this jutsu is properly done, the bijuu would be encased in Crystal bands. Durability of the crystal is 200. Upkeep is an A-Rank jutsu worth of chakra.
Requirements: Learn from Ha

Iron Maiden:
How fast does this coffin form? Because if a person has a higher speed stat then they could react to this.

Sorry it has taken a while to get to this.

Edit: The rest are approved btw
