Before Saturday, the only time Motherwell had lined up in a back three was in their comfortable win over Hibs in November.
Askou deployed that 3-4-3 system again at Easter Road, but on this occasion there was no sustained control from Well in absorbing match, particularly in the first half.
Grant Hanley, who was pointed out as a weak link in Hibs' build-up by Askou two months ago, was a threat from set-pieces, heading wide before Obita lashed over. Elie Youan also put a close-range header straight at the goalkeeper.
The leveller aside, Hibs failed to capitalise on the errors they forced their opponents into, but they made Well suffer with intense, direct play, repeatedly turning Askou's defence.
Without Watt, one of the Premiership's standout players this season, the away side lacked their usual composure but were resolute for the most part and still created numerous chances.
Tom Sparrow and Maswanhise forced Raphael Sallinger into two fine first-half stops before the Hibs man denied Emmanuel Longelo at his near post in the dying seconds.
After a game that could have swung either way, Gray and Askou will settle for a point as the potential to lead stellar seasons continues to bubble away.
