Equipment Name: (Insert First Name) Kurogane Flask
Type of Equipment: Flask
Rank: D (Can get refitted every rank up to equal user's rank)
How Many: 1
Appearance: A black flask with a blood red stopper which melts away and forms a ring around the top of the flask when it is in use. It has a crimson elastic strap which allows the Kurogane to position it on their arm or legs for it to be secured in place and also not be hampered if they transform whether to a bigger or smaller size.
Special Ability: This Flask is given to the Kurogane clan members who pass the Genin Exams and is a useful piece of equipment which aids them in combat. Its special ability is actually weightlessness as no matter how much blood is stored inside of it, it is as light as a feather and consumes no more than it's carry-weight (according to weight limit) while empty. In terms of how much blood can be stored it has two differing amounts with the latter being the max any flask can store; the first which is Min for minimum capacity which is 12 D-ranks worth (2 C-ranks or 1 B-rank) of Blood. The second is Max for maximum capacity which is 36 D-ranks worth (6 C-ranks, 3 B-ranks, 2 A-ranks or 1 S-rank) of Blood. Both have lines so the Kurogane doesn't have to guess how much they should fill it up by, a gray line on the inside of the flask signifies Min and a red line also on the inside of the flask signifies Max.
