A Tyrone final that was level on 11 occasions had a combustible quality that simply had to finish level to satisfy natural justice.
Coalisland appeared to take advantage of Gary Wallace's black card and subsequent red 10 minutes into the second half to finish strongly, but a late raid upfield deep into the fifth minute of time added on ended with Nathan Donnelly punching over to earn Killyclogher a replay, same time, same place, next Sunday.
It was nothing more than they deserved and they might have even captured the O'Neill Cup for the second time in their history had Conall McCann's final effort not drifted tamely wide.
Next Sunday will be Coalisland's fourth week out on the trot as they took two attempts to get over neighbours Clonoe in the semi-final, but they will have to do it without Philip Toner who left the pitch with a suspected broken leg.
The schedule does not bother Na Fianna manager John McKeever.
"Just like last week, it doesn't matter to me," the Portglenone man said to the huddled press pack in the Healy Park tunnel afterwards, as fans of both clubs were left in that suspended reality that a drawn final produces.
"Killyclogher will say the same, when momentum is going we want to be out seven days later. We don't want to wait 14 days.
"We are going to have to work without Philly Toner again next week, but we have a strong bench to do that."
Killyclogher manager Dominic Corrigan rued their own loss of Niall McFadden who injured himself in taking possession of a kickout in only the second minute.
"Niall has been a massive player for us all season, probably the player of the season, and to lose Niall was a big blow, but the boys responded to that," he said.
"Although there's no doubt that Niall was a huge loss.
"The injury looks to be fairly serious and we're sending him to hospital to get him assessed.
"The initial signs would be that we wouldn't be overly optimistic."
Killyclogher started much the brighter, but their shooting was rash, with eight first-half wides.
Scores that did come had to be on the money, one as impressive as the next as Mark Bradley and Conall McCann of Killyclogher got off the mark with superb points, while a Niall Kerr effort sliced off his left brought gasps from the press gantry.
In a tense opener, Padraig Hampsey bust through the middle to score a superb solo point and Brian Toner added a free to give the half-time lead to the men from east Tyrone, 0-8 to 0-7.
The Killyclogher revival at the start of the second half yielded three points, but was instantly wiped out by a Coalisland goal.
Niall Kerr had the presence of mind to deliver a free fast to the isolated Dermot Thornton. He flicked down to the onrushing Cathaoir Quinn who took his time and made sure of his goal, planting it into Sean Fox's net only after the promising custodian had already committed himself.
From that point on,Killyclogher produced another three consecutive points, but were badly hampered when wing-back Wallace was black-carded for dragging down a celebrating Coalisland player after he came out for the kickout after the goal.
Having already received a yellow card, Wallace incurred a red.
As the game went down the stretch, Coalisland were making the extra man tell, and one flowing movement between the outstanding Plunkett Kane, Eoghan Hampsey and Brian Toner ended with substitute Peter McGahan's second point of the evening to draw level with normal time up.
McGahan then caught the resulting kickout and set up Kane for the point that could have been the winner, before Killyclogher's late, late push.
The Tyrone county board will hardly be complaining at the prospect of another bumper attendance in Healy Park for what will be a hotly contested replay.
Tune in next week for more helter-skelter stuff.
