I started thinking whether I should substitute a magickal condenser with a sigil. One of the reasons is that herbs for the condenser won't be growing here till the summer.
Unfortunately I don't know what intent to state for the sigil. Should it be something that makes the sigil the condenser? Or something that enhances effects of the mirror? Or something that enhances my divination skills? Will I be able to use the mirror charging techniques I am used to or will I have to abandon my current system?
