Question on Warding Fetish

One of the effects of Warding Fetish in the passive skill tree is written "30% increased Damage per Curse on you".

Is that 30% more damage taken to your character for each curse on your character?

or

Is that your character does 30% more damage for each curse on your character?

Thinking about using this in a build, but I want to clarify the description as there's a great deal of difference between the two interpretations.

Your character deals 30% increased damage per curse it's affected by.

If it's a matter of damage taken, it's always specified.

Thanks for the response.
