 SPELL SERIES: AVADA KEDAVRA

Purpose: Avada Kedavra (also known as the Killing Curse) is a curse that causes instantaneous death and is one of the three Unforgivable Curses, as well as being the worst one of the three. There is no known counter-curse or cure for it apart from someone else sacrificing him or herself for the targeted person; however, one may dodge the green bolt, use a physical barrier to block it, or intercept the bolt with another spell.

Incantation: Avada Kedavra    

Etymology: Avada Kedavra is based on the Aramaic עַבְדָא כְּדַברָא, avda kedavra, meaning “what was said has been done.” This phrase is also the origin of abracadabra, which, like hocus pocus, is used by magicians as a magic word when they perform tricks. “Kedavra” also sounds very similar to the English word cadaver, which means “corpse,” and derives from the Latin cadere, “to fall.” 

Fact: Only two wizards are known to have survived blows from this deadly curse: Harry Potter and Lord Voldemort. Harry survived two direct attacks: once in 1981 after his mother’s self-sacrificing love protected him from Lord Voldemort, and once in 1998 after the curse, cast again by Voldemort, served only to destroy the fragment of the dark wizard’s soul that lived in Harry. Lord Voldemort remained alive after the aforementioned curse from 1981 rebounded and struck him because of his Horcruxes.

I felt this was the best representation of the Killing curse, an ending heart beat.
