Threeshaper's Cryo-Spear

While cast the user must hold the chunk of ice, in doing so the chunk of ice splinters into small fragments that coalesce on into the shape of a spear in one hand and a small shield or buckler in the other hand of the caster. The spear deals 1d6 + STR MOD piercing damage and 1d8 cold damage, Properties: Thrown (20/60). The shield provides the caster with + 1 AC

If thrown the spear the user can use a bonus action to retrieve the spear in which the spear dissipates from its location. The spear is summoned by grabbing your shield and pulling out which births a new spear.
