The electrum bowl story made me laugh a bit, I had something kinda similar once with a metal tool during a charging phase.
It didn’t blow up or anything, but the timing was just… too perfect …
Do you think it’s more the local season/air charge over there, or the actual structure of the ritual itself?
Sometimes it feels like both things kinda amplify each other.
To me it is more about location within that 'seasonal / air charge ' meaning the location can attract the charge .
Depending on the 'ritual current ' amplification or chaos !
[ When I first got this place , it was already known to be a 'power center' . The reason I got it was no one could handle it - one woman , considering purchase , spent the night here , Said she would never do that again and would not say why . Excited , and having a caravan as a bedroom and other buildings , I set the empty cabin up as a ritual space . Later that day I went out and came back to the whole thing smashed up ! The back door blown in and smashed , glass everywhere and the room and all my stuff looked like a willy-willy* had been through it ! .
After a lot of cleaning up and further learning and some 'adjustments' I tried again . That never happened again ( actually seems protected from such 'weather' events now .]
