Damage Types

[donut3.5]

Hey, I was looking through the triggers, and this question has prodded me for a while.
When you have the trigger Order unit to damage target,
I know what attack type is (chaos, spells, piercing, normal) but what is damage type?
What is the difference between

• Normal
• Unknown
• Plant
• Shadow Strike
• Lightning
• Enhanced
• Sonic
• Acid
• Divine
• Death
• Disease
• Cold
• Fire
• Mind
• Defensive
• Demolition
• Poison
• Slow Poison
• Spirit Link
• Universal

Are they just for more triggers, like

If
Damage type was equal to cold
Then do
Kill Unit
Else
Do Nothing

Or is there some otherworldly point to them?
