The Owls’ unbeaten run continues but how one point was not all three at Hillsborough on Saturday represents the story of the game.
Wednesday dominated Gillingham in all areas, came back from a sucker punch, but could not land the knockout blow.
To compound matters it was former Owls academy striker Vadaine Oliver who bit the hand that once fed before Florian Kamberi eventually equalised.
It could and should have been more but for all their possession, the hosts fell short of conjuring a vital second goal.
It was all Wednesday from the off and one inventive move was a lick of paint away from yielding the opener.
Theo Corbeanu, impressive throughout, played a clever feed to Fisayo Dele-Bashiru down the right and his low cross was backheeled against the woodwork via the improvisation of Callum Paterson.
The Owls pressed and certainly seemed the more likely but were caught cold by Gillingham’s first real attack, which paid dividends 20 minutes in.
Bailey Akehurst’s set piece was flicked on from the edge of the box and Oliver found space to pick up, look up and stroke into the far corner.
Wednesday regrouped and piled on the pressure – Barry Bannan saw a glancing header deflected wide and Corbeanu was twice denied by keeper Jamie Cumming from identical angled hits.
The second half was a blueprint of the first, with Wednesday asking all the questions. Prime outlet Corbeanu fizzed a low cross right into the mix that just missed the onrushing attackers and Kamberi headed another Corbeanu feed over.
Darren Moore introduced Saido Berahino from the bench and the Burundi international played a key role in a move that ended with Patterson slamming yet another Corbeanu feed past the post.
A goal was coming and duly arrived on 76 minutes. Bannan unleased a fierce drive that Cumming could only parry – right into the path of the lurking Kamberi, who was left with the simple task of finding the unguarded net from close range.
Moments later, it was almost 2-1. Marvin Johnson delivered a teasing ball from the left that evaded a raft of bodies and was on its way in until Jack Tucker hooked off the line.
The visitors were pinned into their own half for the remainder of a one-sided contest but try as they might - especially Corbeanu, whose dipping volley with two minutes to go fell agonisingly the wrong side of the upright - the Owls could not muster a winner and had to settle for a point.
