Using abilities through trigger editor

[Zandari]

I've been using Warcraft 3 editor for awhile (doing mostly basic things) and can't figure out how to make a unit cast a custom ability through the trigger editor. I don't know if it is even possible. I have been trying to work it out for the last couple days. I check everywhere online but can't find anything. If any one can help please do...

Simply use this:

• Unit - Order (Last created unit) to Human Mountain King - Storm Bolt (Picked unit)

This will cast a ability that's based on Storm Bolt, even if you have edited and
renamed the spell.

First, you must know its Base Order ID of a Spell
Like Storm Bolt, its Base Order ID or "Order String - Use/Turn On" is "thunderbolt"
So, ANY ability with this Base Order ID will be fired through trigger just like Kala

Thank You very much Kala and Defskull. Everything works perfectly now.

This is a problem with GUI, it obscures the mechanics behind orders.

Each ability uses an orderID. Custom abilities mostly use the same order as their base ability (exceptions are like channel where you can change it to the orders of other abilities). Some abilities and unit actions use hidden orders or orders with no string (like anything item related or item based abilities like wand of illusion) and those must be referenced via their raw orderID (an integer used internally that orderstrings compile into).
