Moon Drake Dagger

Weapon (dagger), rare

This dagger is fashioned from a moon drake’s fang.

You gain a +1 bonus to attack and damage rolls made with this magic weapon.

You can use an action to imbue this weapon with additional magic for 1 minute or until an attack using this weapon hits a shapeshifter. That creature must succeed on a DC 15 Constitution saving throw or take 2d10 radiant damage. On a failed save, the shapeshifter instantly reverts to its true form and can’t assume a different form for 1d4 rounds. The dagger can’t be used this way again until the next sunset.
