Shiver-Spear
Spear, very rare (requires attunement)
This crude-looking spear has a spearhead of solid, unmelting ice. When you hit with an attack using it, you deal an additional 1d6 cold damage. As a bonus action, you can summon the Shiver-Spear to you as long as one of your hands is empty and the Shiver-Spear is within 120 feet.
You are considered proficient with the Shiver-Spear, even if you are not otherwise proficient with spears.
The Shiver-Spear has 10 charges. As an action, you can expend 1, 2, or 3 of its charges when you hit with an attack using the Shiver-Spear. For each charge that you expend, deal 1d6 piercing damage + 1d6 cold damage + your Strength modifier to one additional target adjacent to a target you dealt damage to with that attack. The Shiver-Spear regains 1d6 charges at midnight.
