The thrilling contest was witnessed by only around 1,000 people in the ground after UEFA imposed a stadium ban on Legia following crowd disturbances in the game with Borussia Dortmund.
Real, who had won all seven of their prior meetings with Polish opposition in this competition, had gone 2-0 ahead as Gareth Bale marked his new contract with a goal and assist for Karim Benzema.
But the hosts fought back through Vadis Odjidja-Ofoe, Miroslav Radovic and Thibault Moulin and were on course for a memorable victory until Mateo Kovacic salvaged a point with five minutes remaining.
Real's fastest ever Champions League goal arrived just before the first minute was up as Bale displayed exquisite technique for the opener.
Fabio Coentrao's left-wing cross was headed on by Cristiano Ronaldo and the ball bounced once before Bale twisted his body and dispatched it into the top corner with a knee-high half volley.
Zinedine Zidane's side were certainly on top and Raphael Varane, Bale and Ronaldo all came close from corners while Benzema drew Arkadiusz Malarz into a decent stop.

Real Madrid have won the Champions League twice in the last 3 years but hey, they drew tonight and the world thinks it's a disaster?— Chris Millington (@ChrisMilIington) November 2, 2016
Not gonna lie, I haven't enjoyed Real Madrid since Ancelotti left. It's all about stress these days. Benitez was cancer and Zz is clueless.— Robin® (@CalmaAtCampNou) November 2, 2016
