Traits

Regeneration. Augustus regains 10 hit points at the start of his turn. If he takes damage from a silver weapon, this trait doesn't function at the start of his next turn. Augustus dies only if he starts his turn with 0 hit points and doesn't regenerate.

Special Equipment. Augustus wields a +2 Longsword.

Actions

Multiattack. Augustus makes any combination of two Bite, Claw, or Magic Longsword attacks.

Bite (Wolf or Hybrid Form Only). Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit:26 (5d8 + 4) piercing damage. If the target is a Humanoid, it must succeed on a DC 15 Constitution saving throw or be cursed with lycanthropy. While cursed in this way, the target retains its alignment, languages, and equipment but otherwise uses the werewolf stat block, excluding actions that require equipment the target doesn't have. During any night when there's a full moon in the sky, the target becomes an NPC under the DM's control and remains so until the night ends. A Remove Curse spell or similar magic ends this curse.

Claw (Wolf or Hybrid Form Only). Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit:21 (5d6 + 4) piercing damage. If the target is a creature, it must succeed on a DC 16 Strength saving throw or have the prone condition.

Magic Longsword (Humanoid or Hybrid Form Only). Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit:28 (4d10 + 6) slashing damage.

Bonus Actions

Change Shape. Augustus polymorphs into a wolf-humanoid hybrid, a wolf, or his humanoid form. His statistics, other than his speed, are the same in each form. Any equipment he is wearing or carrying isn't transformed. He reverts to his humanoid form if he dies.

Cunning Action. Augustus takes the Dash, Disengage, or Hide action.

Lore

Augustus is a hulking human werewolf of few words. He shares leadership of the guild with Boss Delour and has a knack for planning heists. Guild members consider him a brutal but fair leader. Some perceptive guild members—like Kathra Bitterwind—have noticed he's become more reclusive recently, and when he does appear, he's restless.
