There is a rune you can use to enhance willpower, but you really should meditate along with using runes. You will not advance at all if you do not meditate.
I also hope you are Dedicated. Because you put yourself in mortal danger doing these meditations without being Dedicated.
If you are Dedicated then it's best to start a daily regiment like this. This is a good place for you to start.

The base number for the Sugil rune is 8, so you would vibrate it 8 times, or 16, or 24, or 32 and so on. Pick whichever number works best for your working. Getting a diamond to go along with the Sugil rune is not necessary.
