Everyone knows Chen needed the elemental powers to complete the andocondria spell, but after the events of season 4 along comes Morro master of wind. Then it that same season Nya is revealed to be the master of water. And the upcoming season just from trailers and stuff we know the time twins were elemental masters of time. Now where I am going with this well why did Chen need the powers of; from, fire, energy, earth, lighting, mind, nature, ice, amber, ext for the spell went he didn't need water, wind, and time? So did he only need certain powers? And if that is the case then are there more powers that we just don't know about? Ninjago has already shown us three that Chen didn't need for the spell who's to say there aren't more
