This item is what the "bayonet" would be attached to (and also a picture of the staff - the Lightning Crystal would be the blue gem):
Set in the head of the staff Heart of the Storm, this crystal is a gem of frozen lightning. It can store elemental energies later use, but in a pinch it can also be used to deliver a shock to anyone getting a little close to Goswin.
