A gritty, last-gasp win on the road is very much part of Munster's DNA by now, but that this latest chapter was written with a cohort of the province's best young talents front and centre stage offered further proof of the bright future that lies ahead.
It wasn't pretty at times, yet we may come to look back at this dramatic victory as a real turning point for Munster.
That they played an hour of the game with 14 men, and still managed to come from 12-7 down at half-time and then overturn a 24-10 deficit with 12 minutes left on the clock, merely added to the sense of importance.
Ben Healy's heroics will deservedly grab the headlines as he delivered in what was his biggest test yet.
Anyone who has been following the Tipperary native's fledgling career will know that he has already proven to be a man for the big occasion, having come up trumps for Glenstal when they won their first ever Senior Cup in 2018, and more recently for the Ireland U-20s and Garryowen in the All-Ireland League.
This was Healy (21) announcing himself on the main stage, and that he and Craig Casey (21) were trusted as the half-back pair when the chips were down deep into the second half, was hugely encouraging.
The impressive duo weren't the only ones to catch the eye either, as Fineen Wycherley (22) and Gavin Coombes (22) came off the bench and added plenty of ballast, as well as more subtle skilful touches.
Munster were dogged, they were determined, and perhaps most pleasing of all, they were intelligent in how they thought their way out of trouble following a tricky opening quarter.
Conditions were poor in Wales and against a strong Scarlets outfit, you could understand the logic of testing them in the air early doors.
Not all of the box-kicks were on the money, however, and while the decision to go to the air on the edge of the opposition 22 was puzzling, Johann van Graan clearly changed the tactics soon after that, as the box-kicking became far less frequent.
Munster can take huge pleasure from outscoring the Scarlets by three tries to none, and with plenty still to work on, it's a solid platform on which to build.
Healy is in pole position to start against Edinburgh on Saturday after he made the most of JJ Hanrahan's off day. Hanrahan was not at his best and Van Graan didn't hesitate in sending Healy on in the 55th minute.
The head coach's faith in the young out-half was fully justified as Healy not only came up with the match-winning kick, but also chipped in with another seven points, including a testing conversion. It's also worth noting just how far Healy's long-range penalty cleared the crossbar by. He possesses a huge boot and an excellent technique to go with it, as he drilled the ball between the sticks with a few yards to spare.
That could be a major weapon for Munster, especially considering the damage someone like Elliot Daly causes with his howitzer of a boot.
Healy held his nerve in wet conditions and has now earned the right to start this weekend. Should he get the chance alongside Casey, it will be fascinating to see how the talented half-backs manage the game together from the off.
Wycherley and Coombes, both of whom have that classic Munster edge about them, are also in the driving seat to be in the team.
Wycherley came up with a crucial turnover on the hour mark when he locked himself into the jackal position and ended a barrage of Scarlets pressure. There was a noticeable shift in tempo when the replacements were introduced, as Munster chased the game but never really panicked.
Casey's service sped up, which allowed Healy to attack the gain-line. Wycherley was a willing and powerful carrier, while Coombes stepped in as playmaker and threw some lovely passes, particularly one that set Damian de Allende away for the break which led to Kevin O'Byrne's all-important late try.
With several more youngsters chomping at the bit for their chance, Van Graan has some welcome selection headaches this week. One game into the new season, it's a good place to be.
