Lulea, making the trip to Gavle from their northern home, were not as well rested as their opponents, having needed six games to down Frolunda in the Semi-Finals, compared to the five Brynas needed against Skelleftea.
But they proved they were up for the fight after a level first period, in which neither side found the net from eight shots on goal apiece, and neither conceded a penalty.
Further proving their mettle, Lulea broke the deadlock midway through the second period. Frederic Allard attempted to pick out a teammate in front of the net, only for the puck to deflect kindly into the path of Brendan Shinnimin, who buried it before goaltender Erik Kallgren could readjust.
Outscoring the visitors for efforts on goal, it looked to be a frustrating evening for Brynas, until nine minutes from the end, when Victor Soderstrom's speculative effort from the blue line took the slightest deflection off Tyler Vesel's stick and deceived Matteus Ward.
The momentum was firmly with the hosts, but the Lulea defence held firm through the rest of the third period and the first overtime.
But five minutes into second overtime, that resistance finally broke when Johan Larsson played the puck across to Anton Rodin, who planted the puck beautifully past Ward to lift the roof off Monitor ERP Arena.
The two sides meet again tonight at the same venue, before Lulea host matches three and four later this week.
