Running a trigger when an item is used?

[ikillforeyou]

I want to run a trigger on the unit that the item was used on, is there any simple way to do this?

My current method is effect > issue order > ability

Event: Ability is run

It's not very efficient, is there an easier way of doing it?

Simply hook the trigger to the player uses effect observable.

Use any player for the source player. Use a specific effect (the one the item runs on use) to reduce scope. You can get all the involved effect units (source, target, etc) using trigger script.

The most simple effect I have found for generic trigger enhanced logic is the set effect.
