Cast (Action) (Instantaneous): You summon an orb of sonic energy to make a blast attack (see Blast Attacks) against a creature or an object within your reach. You have advantage on the Fighting test. If you succeed, the target takes thunder damage equal to your result, and -- if the target is a creature or a loose object -- you can move the target a number of squares up to half your result (round down) in a direction of your choice. The effect of this spell is accompanied by a loud ringing noise.

Once you have cast Thunderclap, you must finish a long rest before you can cast it again.

Note that there is no size limit on the target of your Thunderclap. Do whatever you will with this information.
