Rugby Town's mini-revival of late came to an abrupt halt at the hands of fellow strugglers Boldmere St Michaels at Butlin Road.
Despite Valley's bright start to the game, the visitors asserted their authority as the first half progressed and took a goal lead into the interval, before turning the screw with four more after the break - with David Kolodynski's well-struck free-kick late in the game merely a consolation for Rugby.
The hosts were again without a number of players through injuries, suspensions and international duty - leading to a first start for recent signing Justice Campbell in their midfield.
The first chance of the match saw Caine Elliott's shot blocked on the edge of the box, with Campbell then flighting a cross-shot from the right-hand side just wide of the frame.
Town thought they had taken the lead when Boldmere keeper Callum Smith flapped at a Claudio Dias free-kick to ultimately allow Ryan Sahota to help the ball over the line, only to see the strike chalked off for a supposed foul on Smith.
Another Dias set-piece was taken low down by Smith as Rugby continued to search for an opener, but the Mikes were starting to threaten themselves with their skipper Joseph Hull having a header saved low down by Nykah Liburd-Hines and Owen Parry also firing one wide on the turn.
Jordan Wilson missed out with a header to another Dias delivery, but it was the visitors that dominated the remainder of the half, with Harry Sweeney's slid effort blocked, Callum Gittings shooting well-wide and Ben Usher-Shipway also sending one off-target.
The breakthrough came with just two minutes of normal time remaining in the period, when - after neat interchange play on the right - Boldmere full-back Lewis Allison showed good speed to drive on to Rugby's by-line before squaring to Sweeney to fire home into the roof of the net from close range.
Sahota's wayward half-volley flew way over the bar just before the half-time whistle, but after the break, the visitors were straight back on their game again with Usher-Shipway having a low strike kept out by Liburd-Hines's legs and then the same player missed with his downwards header with the goal gaping.
Daniel Gyasi fired just over after he had cut in from the wing, with Town then left ruing another decision against them in the Boldmere box when Josh Thomas's appeal for a push in the back was turned down.
However, Boldmere as good as sealed the match with two excellent strikes within eight minutes, with Usher-Shipway's low shot giving Liburd-Hines no chance on 55 minutes and Gysai adeptly curling a free-kick in off the upright not long after.
The visitors looked to turn the screw further, and Usher-Shipway put one wide, with Liburd-Hines then pushing away a dangerous cross across the face of the goal from sub Johnny Johnston.
Courtney Lashley's low strike on the turn was gathered by Smith in a rare second-half attacking highlight from Town, but it was soon four-nil after Johnston showed neat feet in the box before squeezing the ball past Liburd-Hines after Andre Brown's had initially struck the frame with his strike.
Liburd-Hines was forced into a rapid retreat to catch a speculative long-ranger from Usher-Shipway as the torment continued for Rugby, but Kolodynski did at least give the home fans something to cheer about when he arrowed his free-kick into the net on 90 minutes.
The four-goal differential was restored in stoppage time though, when debuting sub Omreiki Myles was dispossessed by Parry, who was then unchallenged on his goalwards run before firing home.
