https://forums.wynncraft.com/threads/wynncraft-the-gameplay-update-changeblog-1-powders.140149/ this thread should help you get more familiar with powder. (Also at each powder master place there is a small guide that you can read about powders in)
And assuming you have been gone for a while, I'd recommend you take a quick look at the news section just to figure some of the stuff you have missed.
