Manufacture large amounts of Dead Water.
If you don’t have an ancestral altar, I can recommend the following book: https://smile.amazon.com/gp/product/1413484379/
While some are not naturals with regards to necromantic sorcery, lots of people put out offerings like candles, candies and water for their deceased relatives. You will need some version of this for several steps forthcoming, so that’s something you want to set up right away. (Some of you may have had ancestors who who were soldiers or patriots or politicians, or simply people who would have found the Trump Dynasty objectionable. Objects belonging to them or pictures of them may be of uncommon value in this instance.)
When spirits visit the altar space and feed upon the offerings, they actually absorb the life-giving properties from them and what’s left over is a kind of sponge for luck and vitality, primed to restore that equilibrium from anything they touch.
It looks like normal water, but it’s a magical poison.
Which is why you normally throw away that stuff after about a week, and any spillage has to be cleaned up with Florida Water or something similar.
Or, you can concentrate that stuff by letting it evaporate in pans, then stored in glass bottles, and eventually loaded into spring water bottles or squirt guns, and used as a weapon on relics, people or buildings. Or you can trick rotten people to drink it, or boil food in it.
I call this stuff Dead Water or Anti-Water.
It’s not nearly as strong as Seven Suicide Soil, but a lot easier to manufacture. And it just looks like ordinary water, so it’s sneaky. So, get going on that.
