Initiation Time: 1 bonus action
Range: Self
Duration: Concentration, up to 1 minute
You form water into a long spear and then freeze it in your hands. This icy spear lasts until the form ends. It counts as a simple weapon with which you are proficient. It deals 2d8 cold damage on a hit and has the Finesse, Light, and Thrown properties (range 20/60). In addition, when you use your spear to attack a target in particularly cold environments, you make the attack roll with advantage.
If you drop the weapon or throw it, it dissipates at the end of the turn. Thereafter, while the form persists, you can use a bonus action to cause the spear to reappear in your hand.
