The Bagman

The Bagman has advantage on Wisdom (Perception) checks that rely on smell.

The Bagman regains 10 hit points at the start of its turn. If the troll takes acid or fire damage, this trait doesn't function at the start of the troll's next turn. The troll dies only if it starts its turn with 0 hit points and doesn't regenerate.

The Bagman has advantage on attack rolls against any creature grappled by it.

The Bagman can move through a space as narrow as 1 inch wide without squeezing.

If a creature tries to read the Bagman's thoughts, that creature must succeed on a DC 8 Intelligence saving throw or be stunned for 1 minute. The stunned creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

The Bagman makes three attacks: one with its bite and two with its claws.

Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 11 (2d6 + 4) slashing damage.
