Syrlya's still in the air as the blocks come down, which gives him a vantage point as they close in. He looks up, and then quickly teleports out of the way, further to the corner as the blocks intended to trap him fall around nothing.

One look at those getting trapped, and Syrlya immediately goes invisible. It'll be no good to get trapped because someone's watching for a round two, and hopefully it'll leave him undetected enough to get an idea what the hell is going on.
