If you want this model to have a hero glow, download
this model and attach it using a modified aura, or whatnot. I personally hate hero glows, and refuse to make a model with one.
Then...
Unit - A unit Finishes training a unit
Unit - A unit Spawns a summoned unit
Conditions
((Unit-type of (Summoned unit)) Equal to Type of Your unit) or ((Unit-type of (Trained unit)) Equal to Type of Your unit)
Actions
Special Effect - Create a special effect attached to the origin of (Summoned unit) using Your Model
Special Effect - Create a special effect attached to the origin of (Trained unit) using Your Model
Or something to that effect to attach the glow.
