Curses

Ill Wind: A foul wind blows from the south, sapping the enemy's strength and will to fight.

Let Their Hate Consume Them: All enemies gain 5% stacking bonus damage for each successful attack they make, but they cannot actively defend, and they temporarily lose 5% of their passive defense for each attack.

Curse Item: Pray that an item will be imbued by the dark powers. Cursed effects are random and permanent. There is no way to discover what the cursed effects are other than equipping the item. Sometimes merely having it in the inventory will trigger negative effects. Once equipped, some cursed items can only be removed by Death or Purification.
