Dragon’s fiery breath.

So, I found a demon that breathes fire and deals piercing damage. I thought about adding the "fire breath" ability to it, like dragons have, so it would deal damage through the target, but I realized that this skill is just for description purposes. I thought maybe the dragon model has a specific attack, but I didn't find anything either. How do I make the damage piercing?

I tried to find it in the human champion's data, but it's also empty. I noticed that there are special files in the folder with the skill names; I suspect that something needs to be done with them, but unfortunately, I don't know what.

I never really thought about this before. But I became interested. A quick search through the game folder revealed the following interesting things.
First, I looked at the fire dragon of the Dwarves; its pattern references the dragon pattern from The Dungeon.

At the same time, the Rampart's green dragons have their own pattern...
I think you can just copy the pattern from the green dragons to the creature you're configuring, and it should work.

Or, you can insert a pattern link to the dragon pattern from The Dungeon into the line; this should also work (considering that this is exactly how it's done for the Fire Dragons, where it works).
