Gandrel's Aspiration

Gandrel's Aspiration is an uncommon +1 Heavy Crossbow that grants Advantage against Monstrosity targets and grants the Sacred Munitions class action that Turns Undead.

When Gandrel was seven, he was frightened badly by a vampire spawn during a public burning. Seized by the flames, the creature didn't shrivel up. It swelled and burst like a squeezed leech. Brains splattered the boy's shoes, grey-pink and pulpy. He would never forget it.

The description of this crossbow is almost identical to that of  The Long Arm of the Gur.

Notes included from Feller of Monsters:

The  Advantage granted by Feller of Monsters applies to all forms of attacks against Monstrosities, so long as the weapon with this passive feature is equipped.

Regarding Sacred Munitions:

The in-game description says "Your ranged weapon attacks possibly inflict Turn Undead," but there is actually no saving throw to resist it.
A level 5 cleric using this feature will also have the  Destroy Undead feature applied to their ranged attacks, dealing 4d6⁠⁠Radiant bonus damage to undead targets.
