Living Blade

"I already knew about mimics, everyone does, yet I was still shocked in horror when the sword hanging on the wall leaped at me and grappled me. I managed to unrestrain myself with surprising ease, and then I looked at it. It was seriously hurted, and probably hungry. Maybe naive of me, I gave it one of my rations. After all, I can't blame the hungry for wanting to feed."

For one reason or another, you have managed to tame and/or befriend a mimic. This mimic has a compulsion to shapeshift into weapons, and as so you use it as one. The relationship is beneficial to both, as one gets a weapon and the other food, yet the deal is fragile, as it is dependant on both having something to gain from the other.

Living Blade Spells

At 3rd level you learn additional spells when you reach certain levels in this class, as shown in the Living Blade Spells table. Each spell counts as a ranger spell for you, but it doesn't count against the number of ranger spells you know.

Living Weapon

 When you pick this subclass at 3rd level, you gain a Weapon Mimic, a creature relative to normal mimics, but which can only transform in weapons. This creature has its own stats and can be attacked and be target of spells, this creature also counts as occupying the same space as you. When you take the attack action, you can also replace one of your attack with one of the Weapon Mimic's attacks.

As a bonus action you can change in which weapon the Weapon Mimic is transformed, gaining it's abilities. You can only chose simple weapons that lack the heavy property. When you reach 7th level in this class, you can transform it into any weapon without the heavy property, and at 11th level into any weapon without property restrictions. Furthermore, if it is a ranged weapon and you lack ammunition for it, you can cause the mimic to deal 2 piercing damage to itself to create one piece of ammunition. When you use this ability all attacks with this weapon this turn have a -2 to hit, as the Weapon Mimic's body has not transformed completely.

If the Weapon Mimic dies, you can use your connection with it and part of your flesh to bring it reform it anew. At the end opf a short or long rest, you can spend a spell slot of level one or higher and loose life equal to twice that spell level to summon the Weapon Mimic with four times the spel slot level in HP.
