A last-gasp equaliser from Graham Rusk earned UCD their fifth point of the season at the end of yet another frustrating night at Richmond Park for Pete Mahon's men.
In his programme notes Mahon assured the St Pat's faithful that maximum effort would be applied to bring back that winning feeling in Inchicore, but Rusk's 94th-minute equaliser was a deserved reward for a spirited comeback by the Students.
The dramatic finale capped off a game that took a while to get going. It was 15 minutes before Rusk was presented with a half-chance when he met Mark Langtry's cross with a clever back-heel, but it never had the power to trouble Gary Rogers.
The odd raid by Anto Murphy was about as good as the attacking fare got for the 994 in attendance in the opening 30 minutes, and they were getting increasingly restless.
Ian Daly popped Danny North's flick-on over Gerard Barron's head in the 33rd minute, but Emmet Dynan's flag was raised long before the ball finally settled in the net.
That began a period of possession for the Saints that would eventually bear fruit.
A penalty shout was waved away after Derek Doyle's shot had struck Paul O'Conor on the arm and Shane McFaul twice threatened the Students' rearguard before Murphy made the breakthrough right on the stroke of half-time.
After Danny North had turned Ciaran Nangle with slick feet on the right, his centre to Ian Daly was scuffed by the ex-Man City man, but up popped Murphy to sweep home.
Gary Rogers twice denied UCD from close range as the Students began to get a foothold in the second half. Right at the death Rusk had the home fans slumping in their seats as he blasted home.
