Quick Spill

With daring-do and practiced grace you seamlessly fling an obstacle across the floor with surprising swiftness. With some extra effort, you can distract from the violent intent.

You spread ball bearings, caltrops, or oil into a 5-foot square. If a creature is in the area, it makes a Dexterity saving throw with advantage (or normally if you spend an additional 1 exertion). On a failure against ball bearings or oil the creature falls prone , or on a failure against caltrops it takes 1d4 piercing damage that reduces its Speed by 10 feet until it regains at least 1 hit point
