The Drua had arrived in the nation's capital top of the table after four rounds but the only categories they dominated on Friday night were turnovers conceded and missed tackles.
Vikings winger Andy Muirhead scored the opening try in the fourth minute of the match and from there the home side never relinquished their lead, running in ten tries to one.
Coach Tim Sampson admitted he was surprised at just how well it went.
"It's a dream, you certainly hope so," he said of the way the game played out.
