The Clarets survived 38 shots against them in their last Premier League fixture on the road as a remarkably resilient defensive display earned a point against Manchester United at Old Trafford.
This time, against West Bromwich Albion at the Hawthorns, a stadium where they haven't tasted victory since 1969, Sean Dyche's side leaked goals from the home side's first venture forward.
Where Burnley played the part of Dr Henry Jekyll at the Theatre of Dreams, the roles were reversed in the Midlands as they transformed in to the opposite side of their persona - Mr Edward Hyde.
There have been times this term where the Clarets have been refreshingly reassuring at the back but, against the Baggies, their vulnerability was exposed in catastrophic fashion.
If the game had been played inside a boxing ring, referee Mike Jones would've been required to have stepped in to bring a premature halt to proceedings.
The first hefty blow was landed in the fourth minute and it was the visitors who were the orchestrators of their own downfall.
Dean Marney provided a helping hand for the hosts when diverting James Morrison's cross towards his own goal and Matt Phillips accepted the invitation, turning Ben Mee to thump the ball in to the roof of the net from close range.
The Clarets did forge a golden opportunity to equalise, moments after Tom Heaton gathered Chris Brunt's miscued volley.
Johann Berg Gudmundsson's set-piece was helped on by Mee, striker Sam Vokes headed in to the path of Jeff Hendrick but the record signing failed to hit the target with only Ben Foster to beat.
England's top flight is an unforgiving beast and the Clarets are finding out the hard way that you'll be quickly punished if you don't take your chances.
And, alas, moments after the Irishman squandered the chance to level, Tony Pulis's men doubled their lead.
Brunt prompted the counter from the edge of his own penalty area, picking out Salomon Rondon in the Burnley half, and the Venezuelan striker played in Morrison who travelled towards the edge of the box, unchallenged, before applying a neat finish inside the near post.
By this point the fixture was mirroring the drubbing from two years ago though the Clarets were appearing frighteningly more permeable.
Phillips had a sight of goal from distance but his low, right-footed effort squirmed off the wet surface and crept wide of the upright.
Morrison then had the opportunity to get on the scoresheet for a second time, fluffing his lines after Heaton had gifted the midfielder possession.
Burnley's back four that started at the Hawthorns contributed to the majority of the 20 clean sheets that the club kept en route to winning the Championship title, but you wouldn't have guessed from this latest showing.
A misguided header from Matt Lowton offered West Brom the key to breaching the backline in their next attack but they were let off the hook when Rondon fizzed over the bar from an acute angle.
The former Zenit St Petersburg forward almost wheeled away in celebration with his next attempt as his sumptuously struck shot seemed destined for the top corner until Heaton intervened with a vital fingertip save.
That was the latest addition to the England international's growing catalogue of stunning saves this season, though the Clarets skipper would be beaten again before the break.
Phillips skipped past Lowton way too easily and when the winger's cross reached the back post Darren Fletcher tapped in to a near empty net to make it 3-0.
Unfortunately the situation didn't improve in the second half as West Brom continued to control the game at a canter.
Rondon did get his goal in the 67th minute, though the finish didn't exactly match the beauty of the build up. Not that it really matters.
Phillips, Morrison and Allan Nyom were all involved in the incisive move down the left hand side and Rondon was the man to prosper, turning on the penalty spot and beating Heaton with an effort that ricocheted off Stephen Ward.
Burnley eyed a consolation as substitute Ashley Barnes sliced wide after bringing the ball down on his chest while Gudmundsson's shot soon after proved too hot for Foster to handle though West Brom survived the scare.
And Gudmundsson was denied again when his free kick from 20 yards out was pushed over the bar by Foster.
