Rally

At 3rd level, you've embraced that the best defense is a solid, strategic offense. When you take damage you can immediately try to steal blood from your enemy, regaining some of your health back. When you take damage, the first attack on your next turn can restore your health an equal amount of hit points to ether your fighter level, or the amount of damage you took, whichever is lower. you must attack with a trick weapon or unarmed strike to use this feature.

Morph Attack

At 7th level, you can change the form of your trick weapon faster. When you make an attack with your trick weapon with your extra attack feature you can change the form of your trick weapon as part of your subsequent attack. The weapon stats used for the attack are of the form being transformed into. The first attack and morph attack must both be on the same turn. you can do multiple morph attacks per turn, as long as you still have attacks to use from your extra attack feature.

Firearm Parry and Visceral Attack

At 10th level, you can catch your enemies off guard with a sudden shot from your firearm. When you make an attack with a firearm with your extra attack feature you can use your bonus action to "parry" your target with it. A creature hit by this must make a DC 10 Constitution saving throw. On a failure they are open for a powerful visceral attack and their movement speed is halved on their turn.

When a creature fails its saving throw, your next attack that turn is known as a visceral attack. A visceral attack has advantage to hit and automatically deals critical damage. if your parry activated your Rally feature, your visceral attack also counts towards the damage you deal for it. You can only attempt a visceral attack once per turn.

At 15th level the DC for this feature becomes 15.

Blood Corrruption

At 15th level, blood's full intoxication calls to you, blurring the line between hunter and hunted. When you kill a creature, deal a visceral attack, or take damage while half or less of your maximum hit points you can transform into a monster.

While in this state:

• Your size becomes large.
• Your equipment melds into your new form until you change back.
• Your AC becomes 13 + your dexterity modifier.
• Your unarmed strikes count as +3 magic weapons that deal 1d8 slashing or bludgeoning damage.
•  Your intelligence score is reduced to (21- your fighter level).
• You have resistance to non-magical bludgeoning, piercing, and slashing damage, unless the damage is from a trick weapon.

You must stay in this state until you are knocked unconscious or you are out of initiative. Once out of initiative, you can revert back to your normal form in a number of minutes equal to (your fighter level - 15).

After you use this feature for the first time, you are permanently considered a shape changer, and whenever you kill a creature that bleeds you must make a DC 10 Wisdom saving throw or be forced to transform. 

Blood Frenzy

At 18th level, when you kill a creature, you can choose to have all your attacks have advantage, in exchange for all attacks against you having advantage, for 1 minute.
