Waxing Crescent Magick
Magick performed on the waxing crescent moon is very similar to the waxing gibbous moon (they are both in the waxing or "building" phase) but you should be aware that the closer the moon comes to being full, the more powerful it's potency becomes. This can be useful to know because sometimes we have the luxury to wait a few days until after the half gibbous moon has passed into the more powerful phase, the waxing gibbous phase.
With rituals that require less lunar potency or are the first in a line of several consecutive rituals that lead up to the full moon, you can confidently use this phase of the moon.
For example, a healing performed to ease a cold or mild chronic illness can easily be started during the waxing crescent phase of the moon. However, a more serious illness would be better served during the waxing gibbous phase.
