Strange doesn't have much time to act. As he sees the snow and water get thrown in the air, he steps in front of Nightshade, hands out as he casts a barrier spell, possibly the only useful thing that Portland-Strange has given him.

The air in front of him shimmers for not even a second before the blasts collide with the spell. His magic manages to hold off a large portion of the blast but the barrier cracks at the end, shattering as Strange takes the brunt of the remaining eye lasers straight to the chest. He lets out a yelp of pain at the impact, staggering backwards.

Nightshade's safe, though. That's what matters.
