Well, he'll do his best to duck, and his best is Guidance-enabled?

It's not very hard to dodge.

Some of the other motes seem to... tackle?... the one that threw the snowball, and they buzz around for a bit, bouncing off each other. Other motes continue watching Blai, floating around. Some of them float back off into the storm.

Maybe it's an elemental swarm somehow.

The motes don't appear to calm down over time. If anything, some of them seem increasingly agitated. More of them appear out of the storm. After a tussle, some of them split off and fly west (if Blai can still tell what that is). Another two chase after them after conferring with the rest. The others keep their distance and hover.

Nine minutes later, the storm seems to intensify, and become more turbulent. Some of the motes come back, more of them peel off, the remaining are darting around and floating higher.

One of them—a different one this time—throws another snowball at Blai's chest, then also gets tackled, and a bunch of them ascend up into the storm, out of sight. There's only two or three left lingering by him.

What curious creatures. He doesn't know if they create the storm or just travel with it. Maybe he'll ask next time he stops in a town.

The wind howls one last time, pattering Blai with hail, and then the storm seems to let up more. The last motes flit off, and visibility slowly recovers. But wait, there's few of the blue motes off there in the distance, dancing their way towards him in an odd pattern—they scatter, flying up, and the hailstorm lifts away—

There's a 14-foot-long scorpion barreling towards him!

Does he have time for zero one or more spells before it strikes?

How about one spell. It's got a bit of distance to cover, still, but it's moving pretty fast.

Refine Improvised Weapon, then, and he wants it to be a spear, for the reach and so he can set it against the charge -
