Leinster booked a home Amlin Challenge Cup semi-final against Biarritz with a performance of ruthless efficiency against Wasps at Adams Park, as they won out 48-28.
The fallen Heineken Cup champions were guided to victory on their debut in Europe's secondary competition by a masterful display from fly-half Ian Madigan.
Starting because Jonny Sexton is still out injured, Madigan scored 28 points and he showed sharp footwork to score the second of Leinster's five tries.
The Irish province led by five points at the interval and then punished an error-strewn second half performance from Wasps with Rob Kearney, Mike Ross and Isa Nacewa adding to Gordon D'Arcy's early try.
Sean O'Brien produced a barnstorming performance at openside flanker which will no doubt have impressed the British and Irish Lions coach Warren Gatland, who also witnessed a dazzling first-half performance from Christian Wade.
The electrifying wing, seen by many as an outside chance of making the Lions squad, scored with each of his first two touches as Wasps took the game to Leinster in the opening quarter.
In contrast, Wasps full-back Elliot Daly endured a nightmare evening in front of England coach Stuart Lancaster, making two mistakes early in the second half which ended all hopes of a famous home win.
And Joe Launchbury, pressed into action at blindside flanker, looked a shadow of the dynamic player who shone for England this year as the Leinster loose forwards bossed the breakdown.
The biggest Adams Park crowd of the season were soon on their feet as Wasps scored a scintillating opening try with under two minutes on the clock.
Nicky Robinson, preferred to Stephen Jones for the sharpness of his passing game, picked out Andrea Masi and the Italian centre cut a perfect line between Kevin McLaughlin and Jamie Heaslip to send Wade scorching over in the corner.
Robinson missed the conversion and Leinster hit back immediately, creating a mismatch in the back line and Fergus McFadden sent Gordon D'Arcy past Ashley Johnson to score under the posts.
Statistically, the Leinster forwards were the most effective breakdown unit in the pool stages of the Heineken Cup and Wasps were struggling to match their physicality.
Sean O'Brien ripped the ball off Wasps prop Phil Swainston and Madigan aimed a cross-kick towards Dave Kearney, which bounced kindly for Tom Varndell to run it clear.
Madigan missed a penalty shot at goal - his only mistake of an eye-catching evening - and Wasps were soon in again with Wade making the most of his opportunity to impress Gatland.
Robinson swung the pass to Wade, who left Richardt Strauss floundering on the inside before beating Rob Kearney on the outside to score a sensational try.
Wasps won an important turnover in their own 22 to halt Leinster's charge but it was only a temporary reprieve as Madigan's step caught Launchbury flat-footed and he scooted past Daly to touch down.
Madigan converted his own try and then kicked Leinster into a five-point half-time lead with two penalties, either side of a successful strike from Robinson.
Nacewa did well to preserve Leinster's advantage as he raced back to deny Wade a first-half hat-trick as the two wings chased down Masi's grubber kick into the corner.
But if the signs of Leinster dominance had been there in the first half, they were illuminated in neon lights in the second as the Irish province took control.
Daly had not looked comfortable at full-back all evening and he made two mistakes in quick succession which gifted Leinster 10 points and the match.
The England prospect dropped a simple pass in midfield, allowing Leinster to counter-attack and their pressure led to Wasps conceding a penalty, which Madigan knocked over.
Almost immediately, Nacewa wriggled through some weak midfield defence and kicked ahead. Daly fumbled the ball and Leinster pounced, with Ross driving over to score.
Robinson kicked a penalty for Wasps but Leinster were rampant now. O'Brien, who had enjoyed a barnstorming game at openside flanker, powered clear and then popped a pass off the deck to Rob Kearney for Leinster's fourth try.
Billy Vunipola was sent on and he was harshly penalised for a high tackle, which allowed Madigan to slot another penalty before having a positive impact with the ball in hand.
Vunipola and Johnson both carried well and Tom Varndell gave Wasps a glimmer of hope with a try in the corner but that was soon snuffed out.
Leinster were punishing every Wasps mistake. After Hugo Southwell had a clearance charged down, Leinster moved the ball quickly to Nacewa on Wade's outside and he scored in the corner.
Varndell managed a second try of the night as Wasps turned in a spirited finish but they had been outclassed by a side with a point to prove.
