This is one of my favorite champion in the game of League of Legends, although I haven't played LoL for a long time. Most of the commands I used to create lux's Final Spark are particle commands. It has a range of 25 blocks, but it is easy to increase its range by adding some commands, you only need to understand the composition of the commands, so that you can easily edit this set of commands.
File:
use /structure load final_spark ~ ~ ~
or just use a structure block
