"Level up"-trigger?

"Level up"-trigger?

I'm working on a map and when I was doing some unit movements I found an order that says "level up". It's under the "Unit - Issue Order With No Target" / "Order Unit To Level Up". Can anyone tell me what it does?

Strange, i do not believe a unit can be issued an order to 'level up'.

To level a hero up, i always used hero - set level to (unit level + 1)

I'd say try it out, put down a hero lvl 1, and issue the order to level up, then see what happens.

If that's not it, then i wouldn't have a clue.

I did try it but nothing seemed to happen.
