This is a Thinking particle which is based on Hristo electric arc setup, I added some controls and features like:
-New Tp spline, so you dont need to increase the particle count to make the arc look solid. which made the tool more responsive.
-Noise Scale.
-Animated phase.
-Animation speed.
-Time to reach the target.
-Randomness in scale, speed, width.....
-Absolute control over the manitude place and strength using Value to Value curve, so technically you can draw the sthape of the arc.
-Thickness control over the length of the arc, so it can be bulge only in the middle or have random thickness.
Things to be added:
-Branches
-Liquid form (Like the Harry potter one).
