Castellan Sir Constan Curro

Brave. He has advantage on saving throws against being frightened.

Heavy Strikes. Twice per battle, he can choose to make a successful melee attack deal an extra d8 of damage. 

Evasion. If he is subjected to an effect that allows him to make a Dexterity saving throw to take only half damage, he instead takes no damage if he succeeds on the saving throw, and only half damage if he fails.

Poisoned Blades. All successful attacks inflict poison damage to the target. The target must make a DC 15 Constitution saving throw, taking 24 (7d6) poison damage on a failed save, or half as much damage on a successful one.

Multiattack. He makes three melee attacks or one ranged attacks.

Dwarven Longsword. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: (2d8 + 3) slashing damage, or (2d10 + 3) slashing damage if used with two hands.

Dwarven Spear. Melee or Ranged Weapon Attack: +4 to hit, reach 5 ft. and range 20/60 ft., one target. Hit: (2d6 + 4) piercing damage, or (2d8 + 4) piercing damage if used with two hands to make a melee attack.

Shield Bash. Melee Weapon Attack: +4 to hit, reach 5 ft., one creature. Hit: (2d4 + 4) bludgeoning damage. If the target is a Medium or smaller creature, it must succeed on a DC 15 Strength saving throw or be knocked prone.

Parry. He adds 3 to his AC against one melee attack that would hit it. To do so, he must see the attacker and be wielding a melee weapon.
