If it is spawning units I would just use a few Model actors that are set to a reduced opacity. Use the SOpBasicScopeFollow SOp to get it to follow the cursor and be created by the cursor for the ability. Have the Site Operation (Forward Vector) SOp come second so it faces the caster then use a Site Operation (Explicit Rotation) SOp to get it to face the right way. You then just need to animate it to look like your spawned units when idling and then attach a few more Model actors at offsets hosted from your main one.
