copper lightning storage

It would be cool, now that we have a lightning rod, to be able to store lighntning bolts to then use with our trident independently of the weather.

You could make a crystall ball out of amethyst and copper and by placing it on top of the lightning rod it would charge up once it's hit with lightning. After that you could call a lithning strike with a trident even if it's not raining, however it would be a single use so it woundn't be too overpowered.
