Name: Lusterless Pearls
Rank: D
Magic Cost: 10, 5
Requirements: Lack Luster Limb
Class: Supplementary
Element: None
Cooldown: 2 posts
Duration: Sustain (6 posts), until broken
Effect: After activating the magic by touching the tips of their thumbs together (prerequisite of Lack Luster Limb magic), the user then channels liquid bone into one of their hands. After the liquid bone accumulates to the point of a swollen hand, the magic hardens the liquid bone into multiple pearl sized balls of bone. The hand splits along it's side releasing multiple balls which are explosively scattered in a 5 meter area outwards from where the limb is. They do no damage, nor do they serve to defend against an attack but can be used as something that scatters across the ground and might cause people to trip on them if they don't see them or are chasing the user and running recklessly. There are enough pearls to cover a total of 5 meters in a circular area and they can be destroy by D-rank damage or higher. Unfortunately, the hand used to cast the spell cannot be used for the duration of the cool down of the spell.

Like this but, without the hair, water, and more in context with the wave and how it only covers just his body.

Name: Lusterless Wave
Rank: D
Magic Cost: 10
Requirements: Lack Luster Limb
Class: Defensive
Element: None
Cooldown: 2 posts
Duration: Sustain (6 posts), until broken
Effect: After activating the magic by touching together the user's thumbs(prerequisite for magic), the user's hands leak liquid bone and can be splashed upon a surface by touching both leaky hands to the base, flat and non-flat land, instantly hardening the liquid bone while the user is touching it, to make a hardened shield like wall, large enough to just barely cover the users entire body. The small wall, 5 feet tall and 2 feet wide, can withstand 1C or 2D ranks worth of damage before breaking. This spell doesn't disable the user's arms after use, but if the user is not in contact with the liquid bone while the wall is splashed upon a surface, the liquid won't instantly harden to defend the user.

Yes...Exactly

Name: Lusterless Jab
Rank: D
Magic Cost: 10
Requirements: Lack Luster Limb
Class: Offensive
Element: None
Cooldown: 2
Duration: Instant
Effect: The user extends one of their arms, palm open at a target. As bone liquefies in the user's shoulder, and rapidly flows into the arm extended cutting off the flow at the elbow and pushing the fluid forward through the palm. The liquid hardens into a pole made of bone, an inch and a half in diameter and 3ft long, which extends explosively from the users arm to jab a target causing very little bruising in blunt damage (D-rank).

The attachment would look like this prosthesis.

Name: Lusterless Leg
Rank: D
Magic Cost: 10, 5
Requirements: Lack Luster Limb
Class: Buff
Element: None
Cooldown: 2 posts
Duration: 3 posts
Effect: After activating the magic by pressing both thumbs together (magic prerequisite), liquid bone swells in the user's feet ejecting from the skin and hardening into attachments on the legs that give them speed, like an animals hind legs would, and allows them to run faster- 10 m/s and can dash 4 m/s once per three posts. For a post after the end of the buff, the user's legs cannot move due to the bones in the feet needing to be reformed. (Might have this wrong but if not then cool.)

Name: Lack Luster Spread
Rank: C
Magic Cost: 20 mana
Requirements: Lack Luster Limb
Class: Offensive
Element: None
Cooldown: 3 posts
Duration: Instant
Effect: After activating the magic by touching both thumbs together(magic prerequisite), the user builds up liquid bone and hardens it at the finger tips of both hands(thumbs not included). A build up of internal heat and pressure fires the tips of each finger, no longer than an inch, and a half inch in diameter, at a target (4 on each hand, 8 in all). Since there is no indication of the spell being fired sound wise, besides the sound the objects might make as they soar through the air it makes the user undetectable while the spell is used. The finger tips deal 1/4th D-rank damage each. Altogether they deal 1C-rank worth of damage in the form of moderately deep cuts. The finger projectiles can travel for 10 meters. After use, the user cannot use their finger tips(thumbs not included) for the duration of this spell's cool down(3 posts).

Effect: After activating the magic by touching together the user's thumbs(prerequisite for magic), the user's hands leak liquid bone and can be splashed upon a surface by touching both leaky hands to the base, flat and non-flat land, instantly hardening the liquid bone while the user is touching it, to make a hardened shield like wall, large enough to cover the users entire body and maybe one more of average to small size. The small wall, 6 feet tall and 4 feet wide, can withstand 1B or 2C ranks worth of damage before breaking. This spell doesn't disable the user's arms after use, but if the user is not in contact with the liquid bone while the wall is splashed upon a surface, the liquid won't instantly harden to defend the user.
