Spell with a dummy unit

[Samuro]

I'm trying to make a unit ability that has the same effect as Scroll of Protection - increased armor for nearby allied units. Due to a problem with multicasting, I have to do this with a trigger rather than simply a custom ability based on Item Temporary Armor Bonus. Here's what I've tried:

• Seal of Protection
  • Events
    • Unit - A unit Starts the effect of an ability
  • Conditions
    • (Ability being cast) Equal to Seal of Protection (Paragon)
  • Actions
    • Unit - Create 1 Casting Dummy for (Owner of (Triggering unit)) at (Position of (Triggering unit)) facing Default building facing degrees
    • Unit - Add Seal of Protection (Dummy) to (Last created unit)
    • Unit - Order (Last created unit) to Night Elf Druid Of The Claw - Roar
    • Unit - Remove (Last created unit) from the game

Seal of Protection (Paragon) is a custom ability based on Roar, with damage increase set to zero. Seal of Protection (Dummy) is based on Item Temporary Armor Bonus with the order string "roar" added for "Use/Turn on." When I cast the spell, the buff is applied but no armor increase occurs.

I've looked for tutorials on how to use dummy units and found nothing helpful. This is my first attempt at using a dummy unit and I really don't know what I'm doing here. How should I get this working?

The only ability that let's you change the Order ID of itself is Channel.

What's wrong with just using Roar? It has an armor bonus field.

Also, this should be moved to Triggers & Scripts.

Make a 0.5 expiration timer of the dummy instead of removing it..

Also, set the cast point for the dummy unit in object editor to 0.000, same for cast backswing, or smth like that..

Wow, it actually does have an armor bonus field! I've looked over it several times and always missed that somehow. I guess because I was looking for the word "armor" and it says "defense increase" instead.

Does this mean that changing the Order ID will not function properly? Because the editor does allow me to change it.

The longer you use the editor, the more you realize how redundant some of the data fields are (which is why most people recommend you just trigger a spell so you can have full control of what it does). Take for example "Lightning Effects". There are only about a handful of abilities that actually change from this, but almost every single spell gives you the option to change this.
