[Script] Paralyzing Cask

[Ziadoma]

I am looking for the DotA Witch Doctor Ability called: "Paralyzing Cask".
It shoots a homing projectile that stuns the target it hits and bounces to a random nearby unit and deals damage and stuns the target it hits. It can jump back to the same target after hitting a different target.

I found this: Paralyzing Cask v1.0.6
But the issue with it is, that the projectiles are not homing. They behave very weirdly and unreliable. Are there any other resources on this or can someone please create this spell?

I want to use it for Battleships Crossfire.
