Elemental Magic System Test

This setting is a test for my completely unique magic system based on this world's beliefs about arcane elements and symbology. Water is connected to blood and health, meaning water magic is used to heal or harm people. Air is connected to breath and thoughts, meaning air magic is used to affect the speed people can think and the clarity of their thought. Earth is connected to the feet and movement, meaning earth magic is used to use the ground to propel your steps and boost your move speed or to slow someone down. Cold is connected to a reduction in energy, and can be combined with water to make ice, combined with earth to make crystal, and combined with air to make 'stupor'. Ice Magic can be used to cause damage, Crystal Magic can be used to imprison targets and slow their movement, and 'stupor' magic can be used to slow people's thoughts. Heat is connected to an increase in energy, and can be combined with water to create steam, combined with air to create fire, and combined with earth to create glass. Steam Magic can be used to heal people, Fire Magic can be used to mesmerize people or enflame their emotions, and Glass Magic can be used to increase people's speed or make them slide. Water, Earth and Air can be combined to make Slimes. Slimes are sentient constructed creatures who are imbued with the thought given by air, the health given by water, and the movement given by earth. All magic and combat skills have unique abilities to unlock at levels 5, 10, 15, and 20. Please lmk any feedback you have!
