This armour was designed and made by Ren, it is filled with chakra creating a shield type effect around her so she can handle new scorpions with less of a risk, this would also benefit her in fights, once the items chakra reserve is depleted she must refill it.
Cost:200,000 Ryo. (20 jp item)
Effect: Gives a 20 hp pool donated as "Armour durability", once the hp pool is depleted, she must refill the chakra infused.
Note: cost 200,000 Yen to repair the armour and 20 cp to refill its pool.

Talked it over , this would have to be DR the amount per hit would determine the cost and so would inversal ectra.

Thats fine it could work with dr also.
