This ability is a lovely one to have indeed. By channeling Artemis, you gain a number of boons. First off, you can move the moon around in the sky, making it set/rise and changing its phases. You also gain superhuman strength in the moonlight. In addition, you gain the hunting/archery skills, medical skills (how to prepare remedies) and survival skills of a master (and the power to communicate with and command wild animals). And at night, you will even be able to perceive the future at will.
