Various Tips
Use an item to hold excess spiritual energy after rituals. It serves to make a good reservoir for other rituals. A tip I also learnt is to put the excess energy into the altar and it empowers the altar a greater deal. Of course, energy raised during curses isn't put into the altar but maybe a second item which can then be used in future curses.
Have a pot nearby with some dirt that you've consecrated with the four elements. Then you have a place near your altar that you can bury items in to charge, especially placing them under the moon for a while. A second pot can also be consecrated during the Deipnon and dedicated towards the Holy Dead, which then can become a relatively good substitute for graveyard dirt.
On that note, here's a fun bit from 'Tools of Avernus' by S. Aldarnay on a simple item called the Orcus Casket which can be used to charge items with the energy of the Underworld, or Hades rather. A wooden box is taken and filled some or all of the following: grave dirt, powdered bone (a nice chicken bone may also be buried in the grave and then left for a few nights before being dug up with a prayer and ground up), yew wood shavings (cypress could also be well and good) and baneful or poisonous herbs and plants. You could then probably place it back in the Death-Dirt for another lunar cycle, saying prayers to the Mistress over it for that time before digging it back up and using it to charge items for necromancy.
