I've been playing spark for the past few leagues, and here is the final iteration that I have released for Lake of Kalandra! The video is all-encompassing, and you can go in knowing absolutely nothing about the skill and I think you should be fine!

Here is a playlist of Spark content that is still relevant for upcoming 3.19 league as well, if you want additional resources past this leaguestart video guide (I have culled the playlist of obsolete content): https://www.youtube.com/playlist?list=PLGPotsSEuoQHojDFcXXlg66wxd0VZClLp
