In Glitchtale there are 2 types of weapons: Physical but magically enhanced weapons and purely magical weapons. The latter is stronger but it requires the soul to be super strong and connected with your magic.
For beginners, you’d choose a physical weapon that you will enhance with your magic and use it as a weapon
This would also explain how and why the fallen kids were able to use things like a notebook or a frying pan as a weapon. The clearest example of is how the empty gun is used as a weapon, when you attack with it you clearly “shoot bullets” but it has been stated that the gun has no physical bullets. Which implies the bullets are made of magic and work according to the user’s magical power.
Having your own magical weapon requires a lot of practice along with a natural talent for magical abilities and a strong soul.
