Beam between two units, constant damage (help please)

[Trinketeer]

So i want to make a custom ability that acts as a permanent beam between two units, one is a hero, the other is a minion (or another hero all together).

i am quite amateur at the galaxy editor, and i would be very grateful if someone could point me in the right direction, regarding any SC abilities/effects/behaviors that i could copy from

thanks

The mining laser from the campaign (wing of liberty campaign dependincies required) has a constant damage beam.

Void rays also fire a constant damage beam when attacking but that is more complicated.

The colossus fires a moving beam but that is only temporary.

The mothership also uses a temporary beam.
So do stalkers, but they use two (?) I believe.

Stalkers fire a missle with a ribbon emmiter...

The diamond back from the campaign fires a beam. The heal of marines/medivacs as well as the repair from the science vessal also uses a beam.

Sentries use a beam.
