Do Chests Give out Worse Drops if I repeatedly farm them?

Title says it all - Im after Plagueborn gear- There a locked chest bang outside a town which drops exclusivly Plagueborn. If I keep going at it will I get worse and worse drops?

Anyone know? Been playing ages but just have no idea about this

Ah Right Stilskin you may have missed my point - Im sure I will get AN item but is lets say my first 10 have a 80% chance of being gold and then after that only 50% and get worse?

I have been playing for 1 year and a half now and I have never heard of chests having a less chance of dropping something. Chests always have something in them, and I think since you have to have a key that opens them you don't have to worry about a drop rate of any sort.

Chests that use keys dont,

unlocked ones do i believe
