Chilling Scythe

You draw forth a scythe of ice pulled from the frigid depths of the Shadowfell. This scythe lasts until the spell ends and counts as a simple two handed melee weapon with which you are proficient. It deals 2d8 cold damage on a hit and has the reach property. In addition, undead hit with this weapon take 4d8 cold damage rather than 2d8.

If you let go of the weapon it disappears, but you can draw it forth again as a bonus action until the spell ends.

At Higher Levels: When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d8 for every two slot levels above 2nd.
