Wrote a tool to handle rolling.
It's set to roll Easy, Medium and Hard only, I'm pretty sure no one will write 46,656 phrases anyway
To change which difficulties are being rolled, edit the 3rd line, "1,3" would result in only medium and hard, "0,2" in only easy and medium. Changing the second number there to 4 enables "suicidal".
