Hey!!
So you have a few options if you want to hurt the sn/a/ke. They are often called execrations.
The two top rituals that I would recommend are an extremely long one called ‘The ritual of Overthrowing [the sn/a/ke]’ and ‘Breaking the Red Pot’.
☀️ Breaking the Red Pot
This is a mini ritual that is often performed at Wep Ronpet, it’s pretty simple. You get a pot that is red, or you paint it red, and you write the name of the sn/a/ke on it or draw a picture of it. Then smash the fudge out of that pot. Smash it into a hundred pieces. And throw the pieces away. It is done.
If you want to know more about the theory, there is a whole chapter here:

☀️ The ritual of Overthrowing [the sn/a/ke]
If you’re up for a more complicated ritual, this is the one I would recommend. It will take a lot more prep for and be wary that it takes a lot out of you. I last did this ritual for the birthday of the sn/a/ke and once I was done I was absolutely exhausted and slept for a good few hours in the middle of the day.
The last time I did this ritual I made a record which is here:

You can find the full ritual:

☀️ Etneral Egypt by Richard Reily, pp. 163-175.
These are the only two places that I know of offhand, but there may be more. 🙂

Saying all of that, if you’re not able to do a full ritual. You can always just offer more to your gods, as offering to gods strengths then in their fight.
You can also hurt it by helping the living. Giving to appropriate charities, helping the kemetic community and my UPG is that just living will hurt it. 🙂

I hope this was helpful and please let me know if you’d like me to elaborate on anything 🙂
