A bit extreme but probably possible.
Its not arbitary random as I said you can predict the expected outcome, its percentages like playing a board game with 2 D6 dice as an anology which creates randomness.
So normaly yoy would expect to roll 7s or something near but you can roll snake eyes which many games use to triger a special event or rare event.
So if on the checks the game "rolls" 3 snake eyes in a row something very unusual happens.
Applies to virtually everything in the game I think & is no diffrent to the guy that pulls off a hit with a 2% to hit only to have it bounce off when it should have easily penetrated.
Doesnt happen often but it can.
