What Kinds Of Damage Does Curse Effect?

Today when strolling through Detlas, somebody told me that curse, the water powder special, effects poison. Last I knew it didn't, but to say that I've been an active player is an overstatement.

Does curse effect poison, and, does it effect other sources of damage as well?

I'd like to specifically know:
Poison
Raw melee damage
Raw spell damage
Thorns
Reflection
and damage from the map itself, such as suffocation damage, lava damage, that kinda stuff.

EDIT:
Best answer so far (by @Madkurre thank you very much) :
poison is definitely affected by curse. went on and tested curse on raw melee and spell and none of them are affected. thorns seemed to be affected but it was kind of hard to test, would guess reflection is affected too

 

I know for a fact that it affects poison, not sure about the other's you've mentioned though.

 

Pretty sure curse only affects water damage. In fact, all of the specials affect only elemental damage.

Thorns is neutral or reflected, I'm pretty sure. Reflection is just... reflected, I'm pretty sure. So if the reflected damage is water damage, it's inceraced.
Poison is not affeccted, nor is mapdamage.

Raw melee and spell aren't because it's neutral.

 

thats for armour powder specials. weapon powder specials affect and deal any elemental and neutral damages

poison is definitely affected by curse. went on and tested curse on raw melee and spell and none of them are affected. thorns seemed to be affected but it was kind of hard to test, would guess reflection is affected too

 

Aha, thanks
