Cursed Inferno is a vanilla debuff that deals damage over time to anything it afflicts. The Calamity Mod further augments this by causing those afflicted to have their DR (Damage Reduction) stat multiplicatively reduced by 20%. This effect stacks with most other damage reduction reducing effects. If inflicted on the player, the player takes 20% more damage instead of reducing damage reduction.
