It's a Magic that has the ability to make two or more people's senses as one. If one of the people linked with the Magic feels pain then the others will as well. Although the Magic doesn't actually share the physical wounds, it is still able to "share" death. Extreme amounts of emotion can also be shared such as crying. With this Magic, the user can also create teal Magic swords formed from the user's incredible faith. Using simple arm motions and sometimes verbal commands, the user is able to launch the blades, which then hone in on his or her opponents. The blades are different from normal swords, as they attack the opponent's sense of pain directly, making it possible to slice and damage even Juvia's water body. The user is also able to create different varieties of blades.
- Maguilty Sodom: The user creates teal Magic swords in the air and with a simple arm motion, the user is able to launch the blades, which then hone in on their opponents. The blades differentiate from normal swords, as they attack the opponent's sense of pain directly, making it possible to slice and damage Juvia's water body. Azuma and Rustyrose mentioned that the swords are formed from Meredy's incredible faith. However, the blades can still be knocked away or blocked, as seen when Juvia defended herself with forceful water spells.
- Maguilty Rays: The user materializes and sends forth long yellow blades towards the opponent. The full extent of this spell is unknown, as it was resisted by Juvia's Water Slicer.
- Sensory Link: A spell that allows its user to link two different people's senses to themselves by using strong feelings of some sort between the two people that are being linked to the caster's senses. The linked people are distinguished by a seal that looks like a heart on one of their wrists. The two people being connected to the caster do not have to be near each other in order for this spell to work.
- Three Way Sensory Link: This spell allows the user link with others who are linked by Maguilty Sense, causing pain to be shared by all three of them.
