Clermont Auvergne booked their place in the European Challenge Cup final with a comprehensive win over Newport Gwent Dragons.
The French outfit stormed past a resolute Dragons side, who briefly threatened a comeback, before easing through the semi-final tie.
It is the third time Clermont, who were formally known as Montferrand, have made the Shield final and they will play either Saracens or Bath next month.
The glorious sunshine had indicated an open and exciting game and that is what happened with 11 tries scored in all during a pulsating encounter.
Clermont opened up an early 6-0 lead through two early Bruce James penalties.
But the Dragons hit back in sensational style with try from wing Aled Brew in the 13th minute.
Paul Emerick's break freed Michael Owen and his offload found the on-rushing Brew who had the pace and strength to go over for an unconverted score.
Just as the Dragons thought they were back in the game, Clermont opened their try count as slick handling saw wing Aurelien Rougerie cross under the sticks, with James adding the simple extras to make it 13-5.
It did not get any better for the Welsh side as Clermont hit them with two converted tries in the space of three minutes to almost settle the game.
A botched Dragons lineout saw the ball recycled to No.8 Gonzolo Longo who burrowed over before prop Thomas Domingo crashed through to stretch the hosts lead to 27-5.
The penalty count continued to rack up and it was no surprise to see England official Dave Pearson lose patience and yellow-card Dragons flanker Jamie Ringer.
Emmanuel Etien was also sin-binned for a professional foul just before the break and Adam Black raced through unchallenged to breath some life back into the Dragons as Sweeney's conversion made it 27-12.
It got even better for the Dragons as the impressive Brew collected a chip ahead to cross for an easy run in moments into the second half.
Clermont had switched off but put their foot back onto the accelerator when Marsh pounced in the corner midway through the half to extend the home side's lead once again.
A see-saw contest saw lock Ian Gough cross in the corner before hooker Brice Miguel responded straight away by powering over for the hosts.
And, as the pace of the game slowed, Mignoni hammered a final nail in the visitors' coffin when he ran through for a converted score in the closing stages.
The Dragons refused to lie down though and Dolman won the race following his chip ahead to complete the scoring with a consolation touchdown.
