Instant Kill

Instant Kills are a game mechanic where allies/enemies are immediately killed if certain conditions are met. These are usually rare and usually do not work on bosses in the hands of players, but in the hands of bosses, they are extremely lethal. Instant Kills can be used to defeat pesky non-boss enemies.
