Landeskog increased the lead to 3-1 at 16:20 with a tip of Makar's shot from just inside the blue line on the power play.
Terry forced a turnover in the Avalanche end and scored on a breakaway to get the Ducks within 3-2 at 3:19 of the third period.
"I'm kind of upset it's our last game here," said Terry, a Denver native who played at the University of Denver for three seasons and has scored four of his seven goals this season against the Avalanche. "For some reason, my legs have felt good when we've been here. With me, it's all about my confidence and how I'm feeling. They're a fun team to play. They're fast, they're offensive, and they play a fast game."
J.T. Compher gave Colorado a 4-2 lead at 7:26 with a shot from a sharp angle under Miller's right arm.
Valeri Nichushkin scored from in front to make it 5-2 at 9:30 after Makar went end-to-end, circled behind the net, and passed through the goalmouth.
"Their gap was a little farther back, so I figured I would just kind of take it," Makar said. "I didn't really plan on going around the net, I wanted to try and feed it in front. [Nichushkin] made a good play in terms of driving to the net, and I just kind of tried to throw it around and hope for a good bounce, and luckily it went right on his stick, and he put it right in."
