The Arcanist's Spear

Reaching out your hand, you gather threads of energy into a dimly glowing spear. This magic spear lasts until the spell ends. It counts as a simple melee weapon with which you are proficient. It deals 2d8 force damage on a hit and has the versatile, finesse, and thrown properties (range 20/60). The spear emits dim light in a ten foot radius. This spear has two charges. It disappears once the last charge is used.

As an action, you may expend a charge to use the spear to fire a lance of radiant energy, which hits all targets in a line 30 ft long and 5 ft wide. Each creature in the line must make a Dexterity saving throw. A creature takes 4d8 radiant damage on a failed save, or half as much damage on a successful one.

If you drop the weapon or throw it, it dissipates at the end of the turn. Thereafter, while the spell persists, you can use a bonus action to cause the spear to reappear in your hand.
