Think about a magical sword, it could have different effect when you:
- Hold it in your hand
- Keep it in your scabbard
- When you draw it
- Hold it close to your chest
- When it taste blood
- When you strike it in the ground
- When you pray over it
- When it break (or when a other blade strike it)
Jewelry can have depending effect depending of:
- how you wear them
- where you wear them (neck, ankle, wrist for necklace)
- when they are in their jewelry box
- when you hold them in your hand
- if wear them for a specific event
- when you wear them with a other item
It could be fun to experiment with this.
