Adam Le Fondre's brace helped Reading twice battle back from behind to claim a point against a below-par Derby side.
The Rams struggled to create chances until Theo Robinson met Ben Davies' free-kick with a back-post tap-in.
Le Fondre levelled for the first time with a superb volley but Tomasz Cywka restored Derby's lead when he slid in to meet another Davies cross.
The Royals were behind for only two minutes, with Le Fondre heading home a Hal Robson-Kanu cross to earn the draw.
That extends Reading's unbeaten streak to six matches and it was the least they deserved after controlling possession and territory for much of the match.
Despite scoring twice, Derby failed to find any sort of rhythm for the majority of the evening and have now gone four league games without a win.
Reading, in contrast, started brightly and wasted a glorious opportunity after just five minutes when Mikele Leigertwood charged forward but could only shoot weakly wide with Jimmy Kebe better placed.
Joseph Mills, Kebe and Le Fondre also had tame efforts easily saved by Derby keeper Frank Fielding, who then did brilliantly to keep out a Le Fondre header.
Derby only managed one shot of note before the break, a Jamie Ward back-heel that Adam Federici kept out, but they did improve after the interval.
Robinson was in the right place to turn in their opener before Le Fondre's spectacular reply, but Cywka held off Mills at the back post to put the visitors back in front.
Again, the Royals responded well and Le Fondre got on the end of a delightful cross by Robson-Kanu to power home his second of the night.
