Boss Augustus

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.

Augustus wields a +2 Longsword.

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

Melee Attack Roll: +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 Player Characters as Lycanthropes. 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.

Melee Attack Roll: +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.

Melee Attack Roll: +10 to hit, reach 5 ft., one target. Hit: 28 (4d10 + 6) slashing damage.
