Stone CursedMedium construct
Cunning Opportunist. The stone cursed has advantage on the attack rolls of opportunity attacks.
False Appearance. While the stone cursed remains motionless, it is indistinguishable from a normal statue.
Maneuvers. The stone cursed uses maneuvers (maneuver save DC 13). It has 2 stamina dice which are d8s, a dice limit of 1, regains all expended stamina dice when it finishes a long rest, and regains half its total stamina dice when it finishes a short rest. It knows the following maneuvers:
1 stamina die: spring attack
Petrifying Claws. Melee Weapon Attack: +5 to hit, reach 1 m. Hit: 8 (1d10 + 3) slashing damage, or 14 (2d10 + 3) slashing damage if the attack roll had advantage. If the target is a creature, it must succeed on a DC 12 Fortitude saving throw, or it begins to turn to stone and is restrained until the end of its next turn, when it must repeat the saving throw. The effect ends if the second save is successful; otherwise the target is petrified for 24 hours.
As an action, you can use the Dash action. If you move at least 4 meters straight toward a creature, you can make a melee weapon attack against it. Add the stamina die to the attack’s damage (add half if you miss by 4 or less).
You can increase the damage for each additional stamina die expended.
