Multiattack. Sildar makes two Longsword attacks.

Longsword. Melee Weapon Attack: +3 to hit, reach 5 ft., one target. Hit: 5 (1d8 + 1) slashing damage, or 6 (1d10 + 1) slashing damage if used with two hands.

Heavy Crossbow. Ranged Weapon Attack: +2 to hit, range 100/400 ft., one target. Hit: 5 (1d10) piercing damage.

Parry. When an attacker Sildar can see would hit him with a melee attack, he can roll a d6 and add the number rolled to his AC against the triggering attack, provided he's wielding a melee weapon.
