I have to disagree on this. This is not NA wher your chakra is priceless, here you can easily exchange energy and the whole won is different.
Using katana on Hana is pointless, but i used her even with Katana in 1 or 2 situations maybe.
Using on Yuudai is stupid since he already bleeding form demon rage, and if u dont have healer he is heavily up.
Im using Katana on Jun, and its okay. This way, he needs only 1 random energy on every skill.
My version of katana
Increases damage dealth by demon rage by 10, decreases the cost of blind spot by one strenght energy and decreases cooldown of intercept by 1. Affect the holder with bleeding affliction dealing 15 affliction damage the following turn. This item can only be equipped by the Nirro clan.
PS - Instead of dealing extra 10 damage on demon rage, it can also decrease cooldown by 1. (no cooldown)
You do know village/clan items work UNIVERSALLY for the clan members themselves. Making a village item just to empower its 3 members' unique skills is destroying the concept of village item itself. Like how universal Katana is to the Niiro because it decreases their "specific" skill's strength usage to none at cost of blood.
Also you do know your suggestion will make Yuudai become further OP by making him able to spam Demon Rage as long as I have strength energy and each one hits as hard as 30 damage.
