Phoenix Morphing Order ID?

Is there such a thing? Or is the ability triggered entirely passively? I can't seem to get it to appear in the UI myself.

It doesn't have an order id, it is a passive skill.

Despite being a passive skill it triggers the ability effect events when it morphs.

But there's no way to explicitly trigger the skill, except through the unit's death? OK. Thanks anyway.

Well, since the death of the unit does not really count when you use that you could try to trigger it with KillUnit (although I don't know if that works or if you'd have to use a dummy unit cast a spell to kill)
