Might of the Master. The following numbers increase by 1 when your proficiency bonus increases by 1: the defender’s skill and saving throw bonuses (above), the bonuses to hit and damage of its rend attack, and the number of hit points restored by its Repair action (below).
Vigilant. The defender can’t be surprised.
Steel Defender. In combat, the steel defender shares your initiative count, but it takes its turn immediately after yours. It can move and use its reaction on its own, but the only action it takes on its turn is the Dodge action, unless you take a bonus action on your turn to command it to take one of the actions in its stat block or the Dash, Disengage, Help, Hide, or Search action.
If the mending spell is cast on it, it regains 2d6 hit points. If it has died within the last hour, you can use your smith’s tools as an action to revive it, provided you are within 5 feet of it and you expend a spell slot of 1st level or higher. The steel defender returns to life after 1 minute with all its hit points restored.
Bite. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 7 (1d10 + 2) piercing damage.
Fire Breath (Recharge 5–6). The clockwork dragon exhales fire in a 15-foot cone. Each creature in that area must make a DC 11 Dexterity saving throw, taking 14 (4d6) fire damage on a failed save, or half as much damage on a successful one.
Repair (3/Day). The magical mechanisms inside the defender restore 2d8 + 2 hit points to itself or to one construct or object within 5 feet of it.
Deflect Attack. The defender imposes disadvantage on the attack roll of one creature it can see that is within 5 feet of it, provided the attack roll is against a creature other than the defender.
Description
These intricately crafted constructs are typically made to reflect the forms of the metallic dragons. Plated in brass, bronze, copper, or faux gold and silver, they are often taken for fine draconic statues at first glance. A clockwork dragon makes a formidable guardian or defender, with its advanced intellect allowing it to be programmed with a wide range of orders, as well as being capable of wholly independent reactions to potential threats.
Though most clockwork dragons have a breath weapon that deals fire damage, some might be constructed to deal acid, cold, or lightning damage, depending on their makers’ whims.
