While listening to RPGpundit review one of my recent collections in his video (below), I felt compelled to set the record straight on something...
Pure luck is a dyed-in-the-wool old school concept. You roll the dice and have x% chance of good, bad, or ugly. Like anything else, relying solely on luck can be overused.
Do you know why something like Save vs Death is old school? Because the idea of initiation is ancient.
Not everyone will make it. Some things aren't about preparedness, skill, inborn talent, or - they come down to the luck of the draw... in other words, divine favor. If characters roll well, that means the Gods have given their blessing and certain individuals may continue to prosper. If a particular roll goes poorly, characters die.
The world is cruel, Gods capricious, and fate makes its own choices. That's just the way it goes!
