Douvan took his unbeaten record over fences to three with an impressive display in the Frank Ward Solicitors Arkle Novice Chase at Leopardstown.
Ruby Walsh dictated affairs from the start and the Willie Mullins-trained Douvan proved a willing partner, putting in a superb round of jumping.
Sent off at the highly-prohibitive odds of 1-14, last year's Supreme Novices' Hurdle hero ran his two rivals ragged and put their jumping under pressure from an early stage.
Douvan surged effortlessly clear to win as he pleased by 15 lengths from Velvet Maker. Doomsday Book was another 13 lengths away last of the trio.
The winner was cut to 1-2 favourite from 4-7 for the Racing Post Arkle Trophy at Cheltenham with Paddy Power.
