Just a key.

Name:
Old Key
Rank:
Legendary +
Type:
Key
Description:
A gold coloured key that looks like it comes from a rich mansion.  It can be attached to the Forgotten Old Necklace, though, otherwise, doesn't have any apparent "special" properties to it and isn't known for much.  This was the final item that Seru discovered she possessed, and in fact woke up with it, like the Old Ring and Forgotten Old Necklace.  Like those other two items, the Old Key gives Seru some very peculiar abilities, though, has no use other than that.  Seru is certain that there is more to the key than initially seen, though, it has yet to be proven.  Out of all the items, the key is the most "recent" out of all.

Strengths:
- Despite looking so fancy, it's quite small, meaning it's very easy to hide, especially when attached to the Forgotten Old Necklace.
Weaknesses:
- It will only provide Seru the effects if it's in her possession.
- If the key is seen, it really stands out.  You should be able to figure out the rest.

Abilities:

(A-Rank) Dimensional Aid : This is a very peculiar ability.  When someone does something and Seru desires to react, she is able to perceive an outcome that will annul an enemy attack.  She can then summon an image of herself that performs that action, and by using willpower and lythical manipulation, she can convince reality that she achieved the desired effect.  That mostly works on elementary actions; if Seru has something that can physically deflect a spell, then this ability can work on that, too, though she will still take a quarter of the damage done.  This can be done up to 4 times per post.

(A-Rank) Image Mirror : With this ability, Seru will be able to create an image of and inside of herself.  In appearance, it looks exactly the same as Seru may be looking like in the thread but transparent.  Because the image is inside of her, people normally cannot see it unless it goes out of her, but Seru can manipulate the image to perform actions so long as it doesn’t go further than 5 feet away from Seru.  It cannot cast spells, it cannot be targeted by normal means, it cannot use passives (with the exception of Reflective Guard) or lineage effects (though any effects that affect spells will affect it), and it can attack; the weapon it uses will be the weapon Seru is using at that moment and the damage it can deal will be equivalent to how much damage that weapon deals.  After it has performed its action, it will instantly vanish and return to Seru’s body, and she can manipulate it again.

It’s important to note that the image doesn’t have to fully exit her in order to perform the desired action Seru wants, so if she wants to block a physical attack coming from behind, if she desires, only her torso will come out to block it.  If the weapon she is wielding permits the block of spells, the image can do that, too.  If Seru is using two weapons, the image will be using two as well, and will be allowed two actions instead of one.
