Cast on HP

[Spacey]

Hello, umm I'm making my own map and I'm trying to create a trigger that will make on of my own buildings cast a custom spell when it reaches a certain life

I know about the event for Unit HP. But I can't find any action for the spell casting.

So I was wondering if anyone here could help me. You seem like very helpful people and help is what I need

Just use

Unit - Issue order targeting a Unit
Order <building> to <order> on <target>

where order is the name of the unit that normally has the spell+the spells name, for instance Mountain King - Storm Bolt if Storm Bolt is the spell your spell is based on.

Very confusing in the GUI.

Umm thanks but my spell is based on Starfall and I Can't find any starfall

Could I point out that buildings can't do anything till finished?
And starfall would be found under "Orders with no target"
