Arrow of Freezing

This arrowhead is encased by a blue gem which when broken covers the target in magical ice and hoarfrost. 

When used, if the arrow strikes it's target, it will deal 1d6 frost damage. The target will then have to take a DC12 constitution saving throw, or have it's movement reduced by half for 1d4+1 turns. Once used, the arrow is no longer considered magical. 

The arrow can also be used against other targets such as inanimate objects to potentially freeze them. The arrows will for example, freeze an area of standing water 5ft wide, and 2ft deep for 1d4+1 minutes with magical ice.
