●Curse of Darkness inflicts 1000 damage right after the Spell Card is activated, not when it resolves. If the Spell Card's activation is negated however, such as with Magic Jammer, then no damage is inflicted because the activation was negated.
●Curse of Darkness does not form a new chain and can't be chained to. You can chain to the Spell Card itself, after Curse of Darkness inflicts its 1000 damage.
●Even if your opponent targets your face-up Curse of Darkness with Mystical Space Typhoon, he/she takes 1000 damage before Mystical Space Typhoon resolves and destroys Curse of Darkness.
●When Curse of Darkness is active, and you activate Double Spell, you take 1000 damage for activating Double Spell but not for the target of Double Spell, because it is not considered activated.
●If you send Curse of Darkness to the GY as part of the cost of Emergency Provisions, then Curse of Darkness is no longer on the field immediately after activation of Emergency Provisions, and Curse of Darkness' effect is not activated.
