Weapon (morningstar or halberd) , uncommon

This utilitarian weapon smattered with dried blood has a trigger mechanism that transforms it between a spiked cudgel and a grasping polearm. You can use a bonus action to swap it from a morningstar to a halberd or vice versa.

Transform Attack. When you use a bonus action to transform this weapon from a morningstar into a halberd, your next attack this turn can trap a creature within its spiked head. If you hit a creature with this attack you can attempt to grapple it within the halberd's head. If you successfully grapple it, the creature takes an additional 1d6 piercing damage. Each time the creature attempts to escape the grapple it takes 1d6 piercing damage.

When you use a bonus action to transform this weapon from a halberd into morningstar you can make a single additional attack with the morningstar this turn. If a creature was grappled in the halberd's head when you transformed it into a morningstar, that creature must make a strength saving throw or be knocked prone. The DC is equal to 8 + your Strength modifier + your proficiency bonus.

When the Plague of Beasts swept through the land, the line between man and monster became blurred. It twisted the people into horrible mockeries of the humanoid form that preyed on their kin. To combat the spreading monstrosities, the Hunters rose to prominence, capturing and dispatching the beasts with unmatched skill. However, as hunters looked upon their ranks and saw the mania in their eyes as they maimed and brutalized their prey, they could not help but wonder if they had traded one beast for another.
