Charge.  If the Lord of Blades moves at least 10 feet straight toward a target and then hits it with his adamantine sixblade on the same turn, the target takes an extra (2d10) slashing damage.  If the target is a creature, it must succeed on a DC 19 Strength saving throw or be pushed up to 10 feet away and knocked prone.

Concentrated Intellect.  The Lord of Blades can concentrate on two spells requiring concerntration at the same time, so long as the sum of the spell levels of each spell does not exceed 7.  While concentrated on two spells, the Lord of Blades must succeed on a Constitution ability checks of half the damage received + 5 or 15, whichever is higher.

Attack of Opportunity. 

Clash of Unmaking.  If a creature bearing a Dragonmark (Making) casts a spell that solely targets the Lord of Blades, he can initiate an arcane clash. 

War Casting. When a hostile creature's movement provokes an opportunity attack from the Lord of Blades, he can use his reaction to cast a spell at the creature, rather than making an opportunity attack. The spell must have a casting time of 1 action and must target only that creature.

The Lord of Blades can take 3 legendary actions, choosing from the options below.  Only one legendary action can be used at a time and only at the end of another creature's turn.  The Lord of Blades regains spent legendary actions at the start of its turn.

Attack (Costs 1 Action). The Lord of Blades makes one weapon attack using his adamantine sixblade.

Cantrip (Costs 1 Action). The Lord of Blades casts one of his cantrips.

Blade Dash (Costs 3 Actions). The Lord of Blades moves up to his speed without provoking opportunity attacks, then makes one attack with his adamantine sixblade.  He can make one bladed arms attack against each creature he moves past.

Reforged for War (Cost 3 Actions.  Recharge 6).  The Lord of Blades may reforge a warforged within 20 ft.  The warforged takes on the statistics of a warforged titan (with 65 hitpoints) imbued it with one of the following traits, determined by a 1d4 roll:
(1) Assassin - Once per turn, the assassin deals an extra 14 (4d6) damage when it hits a target with a weapon attack and has advantage on the attack roll, or when the target is within 5 feet of an ally of the assassin that isn't incapacitated and the assassin doesn't have disadvantage on the attack roll.
(2)  Forger - Once per combat, the forger can create a magical protector cannon.  The cannon emits a burst of positive energy that grants itself and each creature of the forger's choice within 10 feet a number of temporary hit points equal to 1d8 + its Intelligence modifier (minimum of +1).
(3) Mage - Once per turn, the mage can cast counterspell as a reaction.  The counterspell is always cast at 3rd level, but uses the Intelligence modifier of the Lord of Blades in its casting.
(4) Pugilist - Once per turn, as a part of a melee weapon attack, the pugilist can attempt to stun its target.  The target must succeed on a DC 15 Constitution saving throw, or be stunned until the end of the pugilist's next turn.
