I just finished the Lightning Arc Spell for the Wind Element. This spell had me the most concerned with particle effects (Chain Lightning was too long to fit on the buttons after I got everything in game).
I never could wrap my head around exactly how you make it look like it’s one continuous jumping beam, but I think it turned out pretty good! I had to make a lightning particle effect and calculate the position, rotation and length needed to hop to the next closest game piece that was of the same type.
