• Adjustment: The user snaps their fingers and chants the spell name causing a magic seal to appear clearly behind their head. The spell causes the user's eyes to start to glow dark purple and grant them thermal vision within 5 meters. But instead of the red marking the highest temperature to blue marking the lowest temperature, because of the Kuro hi mahō effect this thermal vision will show bright purple marking the highest temperature to dark purple marking the lowest temperature.

• If you look at the end of the adjustment, you will see part of the effect of Akuma no ayumi here. That’s because it is how you would apply a dash spell that functions in the air.
  
• Adjustment: The user snaps their finger and chants the spell name causing a magic seal to appear beneath their feet. The spell causes Kuro hi(black fire) to be seen around the user's feet. This allows them to propel themselves in any direction up to 5 meters at their lunge speed and leaves a black flame trail trail behind them. This spell can be used midair to change direction or to resist momentum (e.g. falling from the sky, or knockback up to 5 meters).
  

悪魔の歩み Name: Akuma no ayumi Rank: D Mana Cost: 25 Requirements: Kuro hi mahō Type: Suplementary Element: Darkness + Fire Range: 5 Meters Cooldown: 1 Posts Duration: Instant Effect: The user will have to snap their finger and say the spell name to summon two magic seal beneath their feet, allowing the user to walk anywhere (e.g. water, air, wall) and restrict forced movement(e.g. falling from the sky, knock-back).

• Spells lower than B-Rank cannot have flight capability. It also wouldn’t allow for several different effects to be loaded into this spell.
  
• Flight, Surface Walking, and Dash spells are all independent spell effects that can’t be combined into a single spell, especially not a D-Rank. In this case, the description of the spell is for surface walking, so it would be limited to that effect.
  
• Please change the range of the spell to self as it is granting yourself an effect and the range is not limited.
  
• Adjustment: The user snaps their fingers and chants the spell name to summon two magic seals beneath their feet. This spell allows the user to traverse walls and the surface of water as if on flat land.

This Kuro hi around the weapon will increase the user strength in D-rank state.

• You will see below that I adjusted the casting motion to be more universal. This is just for the sake of not overcomplicating the spell and letting it be easier to understand.
  
• Adjustment: The user swings their arm downward to their side while chanting the spell name causing a magic seal to form above their fists or weapon if one is wielded. The spell causes black flames to shroud the user’s fists or weapon and provide a D-Rank buff to their Strength stat.
