Your Charisma score increases by 2, and one other ability score of your choice increases by 1.

A sentient weapon can be of nearly any age. Many famous weapons were created in ancient times but new ones continue to come into being. Whether you are a long forgotten relic or new from the forge, you are sustained by a magically binding purpose and suffer no effects from the passage of time until your task is complete. You are immune to magical aging effects. 

Sentient Magic Weapons are as varied in nature as any other being. However they do tend to embrace their purpose or moral vision in an extreme manner, driven by the purposes that sustain them. Whatever their alignment they are often inclined towards living out a very particular code or outlook.

The size of your manifested body is Medium. Set your height and weight in keeping with the body's form.

In your manifested form your base walking speed is 30 feet.

Your physical form is unaffected by many of the needs and vulnerabilities of humanoid life, represented by the following benefits:

• You have advantage on saving throws against being poisoned, and you have resistance to poison damage.
• You don’t need to eat, drink, or breathe.
• You are immune to disease.
• You don’t need to sleep, and magic can’t put you to sleep.

You are driven by some great purpose or goal and do not require sleep. When you take a long rest, you must spend at least six hours in an inactive, motionless state, rather than sleeping. In this state, you appear inert, but it doesn’t render you unconscious, and you can see and hear as normal.

Impatient for some mortal to come and fulfill your purpose you have instead learned to shape a body from the incredible will and magical essence within you. Your body has a consistent race and appearance determined by you at character creation. It can range from indiscernibly realistic to the clearly magical but it always appears with the same features unless you disguise them by other means. Except where otherwise noted it functions normally. When you summon your body your weapon form must remain in its hands or on its person or it will dissipate. Your body has advantage on saving throws or ability checks to avoid being disarmed while it is wielding you.

Any items you equip or carry on your body remain attached to it and reappear with it when you summon it. You can emulate the magical properties of a specific weapon by spending a long rest in contact with it. If the item leaves your person through some means you lose these traits until you reclaim it.

As an action you can voluntarily relinquish your humanoid form and exist solely as a weapon. In this state, you retain your hit points and other statistics but can not take physical actions under your own power. Your size and weight changes to one appropriate to the type of weapon you are. In this form you have a wobbling and limited form of magical self-propulsion, you have a walking speed of 10 and can ignore difficult terrain caused by obstructions on the ground. When you are motionless in this state you have advantage on Charisma (Deception) checks to appear as an innocuous item.

When you are knocked unconscious your magical energy becomes unstable and your body wavers in and out of existence. If you are killed your body dissipates and you go into a catatonic state. Any items you were carrying spill out into adjacent squares. Magic that can bring back the dead immediately restores you to sentience.

While in weapon form you can be wielded as a weapon by a creature. If you are a ranged weapon you produce your own ammunition. As a reaction you can impose disadvantage on all the wielder's attack rolls using you until the start of your next turn.

When you are conscious and equipped by a willing and informed wielder you can impart to them some of your skill and power. They are considered proficient when wielding you. Your movement speed is reduced to 0 and you are considered to be sharing a space with them. Attacks, spells and abilities can target either of you as normal though you both share the result of the wielder's dexterity saving throws against area of effect abilities. On your turn you can takes actions but you can not move. The wielder can provide somatic components for your spellcasting if they have a free hand and you count as an arcane focus for your own spells.

First and foremost you are an item of intense magical power. Maintaining your body takes much of your power but you can still tap into your internal reservoir of energy to enchant your edge or point with deadly magical force. Beginning at level 5 as a bonus action you can gain the effect of the Magic Weapon spell. For 1 hour you function as a magic weapon with a +1 bonus to attack rolls and damage rolls. At level 9 this bonus improves to +2 and at level 13 it improves to +3. You do not need to concentrate to maintain this ability but it is subject to dispel magic and counterspell effects.

Resting and healing magic can help restore the animating magic within you similar to organic healing. Since you do not possess a humanoid physiology the Medicine skill does not affect you, the Arcana skill or an appropriate tool proficiency check can provide you with similar benefits.

A Healer's Kit does not provide any benefit to stabilize you but you can also be stabilized by a casting of the mending cantrip or a successful DC 10 Intelligence (Arcana) check.

You can speak, read, and write Common and one other language of your choice.
