Furniture

From flipping over a table to using a gong as makeshift shield, a movable piece of furniture can be manipulated to create partial cover for a short period of time. A creature that is adjacent to the piece of movable furniture can attempt a Strength check as a move action to gain cover from the item until the start of its next turn.

The DC of the Strength check depends on the size of the furniture. The base is DC 10 for size Small furniture, and the DC increases by 5 for each size category over Small (moving a Medium piece of furniture is DC 15, moving a Large piece of furniture is DC 20, and so on). A creature cannot attempt this manipulation if it is two or more size categories smaller than the piece of movable furniture it wants to manipulate.
