Random Number Generator
From Twilight Heroes Wiki
The random number generator is a very very very very very very very very very very evil thing. It is the thing that makes the enemy critical you when you're one hit from victory. Or makes you fumble yourself 5 times in a row, and to death. RNG is the very essence of evil and stuff... All major villains look up to it with teary eyes.
Also, RNG is a bot in chat. See it's page for more information.
