Puts a yellow-orangish aura around the blades and traps that have been enchanted with Sharpen Blade and Potent Trap so you do forget what kind you have up
This is actually a nice idea for the blade/potent enchantments! I sometimes forget if I bladed myself a enchanted blade or not, but there is a way to figure this out! If you hover over your your position icon (sun/blade/etc) at the time of battle, it will show you what kinds of blades and traps you have on at the moment.
Colors will mean: White - It is a regular blade/trap Yellow - It is an enchanted blade/trap
I believe blue means protected blades/traps but I might be wrong here, there is also a color for blades given by your pet as well.
I think its White is normal White is also item card blades but they usually have a slightly higher value
Purple is enchanted Yellow is TC Blue is protected
not sure on the pet blade since I never used a pet with a blade card but I know that the enchanted armament pets' sharpened blade is the same colour as the normal sharpen but they show as different blades and can be used together
