Magic isn't affected by silence because magic is a mute thing. Silence affects alchemy for transmutations and stuff. Magic is pretty accurate as the geomancer in final fantasy tactics as it's not that strong but VERY useful because it bypasses a lot of laws. If you had plans to update the geomancer then you will find 100% accuracy. Magic works best when it's raining and when the orchestra music matches the rain sound effect but acoustics doesn't really amplify magic, it's just what triggers a healthy flow of chemicals in the brain Magic, alchemy and psychic talent work simultaneously as an equation which is why the geomancer using geomancy can use the elements and statuses free of charge. The only thing missing is that magic can repeat itself for a double effect and has a chance of healing the user with drain or syphon/ osmose. You develop magic from healthy spending habits. You can have a loose budget but in your mind it's ingrained how your earnings are spent so it would help if you have redirections of things like rent, power, wifi, gas and water etcetera so you never see that money in the first place
