Samu Manoa's late converted try left honours even between Gloucester and Northampton in a brilliant game at Kingsholm.
Gloucester blew their visitors away in the first half with three penalties for Greig Laidlaw and tries for Charlie Sharples and Richard Hibbard.
Northampton's only reply came through three penalties for Stephen Myler, which meant they were trailing 23-9 at half-time.
The home side scored another try in the second half courtesy of Dan Murphy and there was another penalty for Laidlaw.
The champions regained their pride in the final 40 with two tries for James Wilson and one for Manoa, along with a penalty for Myler, to secure the 33-33 draw.
Myler claimed the first two penalties of the game to give his side a six-point lead but then Laidlaw replied with three of his own.
A fantastic break from James Hook put him in some space to kick the ball across to the wing, where Gloucester had numbers on the outside. Sharples collected the ball and dived over the line.
Northampton's Wilson was shown a yellow card on 27 minutes and the home side took advantage of the extra man. From the lineout, Gloucester took control of the maul and drove Hibbard over the line to score the try.
Myler claimed a penalty on 40 minutes but his team were still trailing 23-9 at the break.
Northampton got the second half off to a fantastic start when Wilson ran the ball in easily over the try line after the massive overlap opened up space for the chip kick to find the centre.
However, Gloucester were quick to respond after building up some momentum on the visitors' line, Murphy had the strength to reach out and score the try.
The Saints replied to that within three minutes when Wilson went over for his second try, well and truly making up for his earlier yellow card.
Myler secured another penalty for Northampton to bring his side to within just four points of their opponents.
Laidlaw then added one of his own just after Gloucester had a try disallowed for a knock-on. On 78 minutes, Northampton drove Manoa over the line in the maul from the lineout and his try secured them the 33-33 draw thanks to Myler's conversion.
