Construct Combiner - Left Leg

Blasting Off. (Arm Mode Only) While in Leg mode the construct flies via rocket propulsion. After transforming to Leg Mode or at the start of it's movement all creatures within 5ft must make a DC 15 Strength Saving throw. On a fail they are pushed back 10ft and take 7(2d6) fire damage. On a success they take half damage and are not pushed back.

Combine! Brute Justice. When a Construct Combiner - Body uses it's Brute Justice ability the construct can immediately use it's Brute Transformation ability to enter Leg Mode (if it is not already in it). It can also then move it's full movement towards the Construct Combiner - Body and combine with it. While combined the construct has a movement of 0 and it can only use it's action to separate from Brute Justice.

Brute Transformation. As an action the Construct can transform between Leg mode and Humanoid mode. In Leg mode the Construct gains a flying speed of 50ft but loses it's walking speed. When transforming from Humanoid mode to Leg mode the construct takes flight through rocket propulsions. See it's Blasting Off trait for the effects for this. While in Leg Mode the construct has the shape of a single leg the size of it's whole body. 

Slam (Humanoid Mode only). Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 8 (1d8 + 3) bludgeoning damage. 

Rocket Stomp (Leg Mode only). Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 18 (3d8 + 3) bludgeoning damage. While in Leg Mode if the Construct moves 15ft in a straight line towards a target it can attempt to make a Rocket Stomp. On a successful attack roll the target must make a DC 15 Strength Saving throw. On a fail they are knocked prone.

Shock Protocol. On taking damage the construct can discharge electricity shocking the attacker. When hit with a melee attack the attacker takes 7(2d6) lightening damage. When part of Brute Justice the construct can use this reaction anytime any part of Brute Justice takes damage. Also while part of Brute Justice the damage is increased to 18 (5d6) lightening damage.
