What is an Invincible accessory, what does it do, where can I find it,..

An invincible accessory it is a special accessory that gives you the [BREAK DAMAGE LIMIT] ability that makes you inflict more than 9999[it depends on how much str you have] Damage.You can find it at Kilika Village look for a guy that has a camera that is looking at one of the New youthleague Headquarters.When you talk to him he tells you that it is in construcion and if you want to look at it.Tell him yes and you will observe at the headquarters,look at it for at least 10 or 15 seconds.Repeat this process at every chapter going to kilika village and doing the same thing.Finally in chapter 5 when you talk to him he will tell you that the new headquarters is already finished and then he will ask you if you want to go there pick YES.When you are there try to look for a treasure chest open it and you will recieve Invincible accesory.[when you get to that place every thing will be hard to see just try looking for the treasure chest when you get there.I hope I helped?
