Eryn And Eryell, Sister Blades

Eryn

Parrying Dagger, Rare (requires attunement)

This small parrying dagger with a flamed blade is made out of a black metal with silvery shards shining bright even in the darkest nights. A thorny stem snakes on the core of the blade. It is always cold to the touch, but hums with life. This weapon is considered silvered.

Emprisonned Soul. This parrying dagger lets you use the following abilities. It can hold up to 3 charges, and gains one charge each time you successfully pary an attack from an hostile creature with it. While an effect is active, starting a new one immediately ends the first.

Protective Sister (1 charge). When you are hit, as a reaction, you gain a +5 bonus to your AC until the end of your next turn, potentially turning the hit into a miss. Eryn materializes from you, her dagger in hand, and attempts to block every incoming attack, her body moving so fast it leaves afterimages.

Harassing Blade (2 charges). When you hit with an attack using Eryn, you may choose to direct Eryn to continue the onslaught. For 1 minute, at the end of your turn, it must decide to move 5ft in a direction of your choice or take 1d4+2 cold damage. This movement provokes opportunity attacks. Eryn jumps out of the dagger, harassing a foe, attempting to stab it again and again and again...

Free Ghost (3 charges). As an action, you temporarily let Eryn free of her cold steel cage. You summon Eryn in a free space within 5ft of you. She acts at the start or the end of your turn (your choice when you summon her). If her HP reach 0 or after 1 minute, she goes back into the blade.

Sentient. Eryn is a neutral good weapon with an Intelligence of 13, a Wisdom of 12 and a Charisma of 13. She has hearing and darkvision out to a range of 40ft.

Eryn communicates with its wearer by speaking aloud. She can speak, read and write Woiselesh and Valleroi. If equiped when sleeping, she also shares the dreams of her wielder. Eryn's voice is clear and soft.

Personality. Eryn is a particularly vivid sentient weapon, often speaking with the people around her or gently humming songs in Woiselesh and Sylvan. While she is shy around strangers, she is a dynamic and upbeat child and hates to be lonely.

She wants to be with her big sister, Eryell, but also to live wonderful adventures. She looks down onto senseless violence but she doesn't like gnolls. She wants a wielder she can consider as a friend, but like any child, she is prone to tantrums. She dreams of being able to eat some cake again.
