Sacred Trick-Hammer

This longsword is sheathed into the handle of an enormous warhammer head.
When the sword is put into the hammer it loses the Versatile property and gains the Heavy and Two-Handed properties, dealing 1d10 bludgeoning damage.
The large hammerhead of this weapon is the sheathe. The longsword component is unique to the sacred hammer and losing either renders it effectively useless as a Trick Weapon. A ritual can be performed to attune the hammer to the sword, however the sword must be of magical quality.
Proficiency with a longsword allows you to add your proficiency bonus to the attack roll for any attack you make with it. Proficiency with a Warhammer allows you to add your proficiency bonus to the attack roll for any attack made when the sword is sheathed.
