So the moon makes waterbenders stronger, especially the full moon, and the sun makes firebenders stronger, along with comets. What about air and earth? Can anything happen that makes their bending stronger? A certain kind of rock or something? I've been wondering this for a while, and they never said anything (at least that I noticed) in the series.
