When this Item is used, it may be placed anywhere within Adjacency as a Double Action, or thrown as an Action.
If thrown, nominate a location and perform an Athletics (or specified on the Item) Check VS the DC of X (Where X is listed on the Item), if the location is outside of Optimal Range then make the Check with Disadvantage.
If placed or thrown successfully, you place the Item's effect, centered on the nominated location, otherwise the GM places it wherever they deem reasonable instead.
