A Curse is a type of spell or hex that inflicts some kind of magical damage or plague on a victim.
LeChucks Cursed Diamond RingEdit
Pox of LeChuckEdit
When Guybrush Threepwood stabbed LeChuck with a faulty Cursed Cutlass of Kaflu it released a terrible pox on the Gulf of Melange which turned many people into violent, green skinned monsters. Somehow it only affected pirates.
