One of the main reasons why assassinations work was because of the assassin's ability to deal an enormous amount of damage on an unguarded target that would more often than not kill the target.
And that particular ability rested upon one very foundational requirement.
Stealth.
The assassin had to remain undetected until the moment he strikes.
And as soon as the assassin made his move, more often than not regardless of whether he succeeded in killing his target, he would have to try and flee.
Assassins are not built to stand their ground and fight, and in most cases, their high value targets would be surrounded by powerful guards, which makes sticking around very dangerous for them.
However, albeit very rarely, some assassins were so up and away more powerful than anything that their targets and their target's minions could muster, that they could simply remain at the site of the assassination and unleash a full massacre.
These were the elite of the elites.
