Ice dagger

Ice dagger was an evocation spell used by arcane spellcaster in the Forgotten Realms.

Effects
Using a few drops of water, the spellcaster would shape a dagger-shaped shard of ice, which would then launch itself inerrantly at a target within close range and explode upon impact, causing cold damage to the target and an area within a five-foot (one-and-a-half-meter) radius.

Components
This spell required both verbal and somatic components, in addition to the drops of water, which must also have originated from melted ice.
