Joe Rowley levelled in stoppage time at Hayes Lane.
Chesterfield came from behind twice last night to secure a point at Bromley.
The six-goal thriller finished 3-3 in London, leaving the Spireites five points clear of the National League relegation zone in eighteenth.
Jerome Binnom-Williams gave Chesterfield the lead just before half time, with the visitors beginning the game in a promising fashion.
The header was Binnom-Williams' first goal for the club.
However, Bromley found a way back into the match on fifty-six minutes, when Roger Johnson nodded the hosts back level.
JJ Hooper then put the home side in front just four minutes later with a well struck effort.
Despite that, with eight minutes remaining, Scott Boden scored his fourth goal in just three matches to level proceedings.
Hooper then went on to notch his second and seemingly secure the points for Bromley on eighty-seven minutes, until Joe Rowley equalised at the death.
Following the match, Chesterfield manager John Sheridan highlighted areas where his side need to improve; "We make life so, so difficult, just through our decision making."
"We make the wrong choices too often, and we got punished tonight for them, but luckily we did show enough character to come from behind twice."
