The other day I did obsession it started off very low the flame, and I let it burn over night the next morning I wake up and the flame burned the whole candle out and part of the picture under it and left a black burnt mark on where I placed it. Is it possible that it ruined the spell? I’ve done the conjure and other candles and left it while I’m sleeping and this has never happened before just this particular candle.
No it didn't ruin the spell.. the spell is complete when the flame is gone. I've had candles to burst and do that also
