Sword when hitting lit yellow (The Witcher 3: Wild Hunt)

In the sword there is a stone? While in the sword of the stones on the sword begin to hallowed and sanctified the runes in the color that is inherent in the stone. Or if different stones, the color mixing of the colors of the stones. And swords do not glow, I have not seen such.

Can you use the sword Arondit ? With each stroke it glows brighter.

Have Arondite clear there property. And indeed it is clear unique swords properties so it makes sense that they are different, but here the question is about why ordinary sword or legimacy to glow.

Several reasons. You put the runes, you enchanted it with a wizard, you use a special ability, type slam, or a special sword with special properties, such Arondite.

How many more stupid questions will be at the expense of the Witcher...
