Ball Bearings You can spill the contents of the packet or pouch to spread tiny metal balls across the floor. A creature moving across an area covered with ball bearings must succeed on a DC 11 Dexterity saving throw or fall prone. A creature that notices the ball bearings can move at half speed through the area to avoid falling prone. A single pouch of ball bearings covers a 10-foot-by-10-foot area.
