We had to wait until after the quarter hour mark for the first half-chance. Taylor Steven contorted his body to meet a corner but his effort drifted over.
Addis almost set up a very Gormley-esque goal when the veteran hitman cushioned his long ball but scuffed his attempted chip.
However, that was merely a foreboding for what was to come as a quickly-taken free-kick by Ronan Doherty put Gormley in behind and he finished with aplomb from a narrow angle.
Larne struggled to get anything going in the first half and were lucky not to go further behind just before the break when Rory hale curled an effort just wide.
The second half was much the same as the visitors looked comfortable and quick-fire headers from hale and Luke Conlan almost extended their lead again.
It took until the 70th minute for the hosts to trouble the away goal but an Odhran Casey block denied Joe Thomson before Benji Magee couldn't stretch quite enough to reach Paul O'Neill's cutback.
With the clock ticking down and the home support's frustrations growing, an equaliser came on 88 minutes. Two subs combined as Conor McKendry's free-kick to the back post was nodded down by Ryan Nolan and it squeezed through David Odumosu's legs and in.
There was still time for late drama as Jonny Addis picked up two quickfire bookings in stoppage time as did a Cliftonville coach but the visitors ended up holding on for a draw on the road.
Both sides are on the road to Championship opposition in League Cup action on Wednesday night with Larne at Annagh United and Cliftonville at Armagh City
