Ballpoint Bolt

Crossbow bolt with a unique tip that is near perfectly spherical. The tip is black and explodes on impact. Each creature within a 10 foot radius where the arrow hit must succeed on a DC 15 Dex saving throw or take 5d4 force damage. A sphere of transparent force then encloses the area for 30 seconds. Any creature that failed the save and is completely in the area is trapped inside the sphere. Creatures that succeed on the save or are partially in the area are pushed from the center of the sphere until they are no longer inside. An enclosed creature can use its action to push against the sphere's wall, moving the sphere up to half the creatures walking speed.
