What is chest running?

I'm just wandering what is chest running?

I've seen running builds for it and i'm just wandering if its when you buy a key and then just run to a chest and open it? Is that all it is?

You answered you own question hehe,you can take several keys to find all the chests in a area.Yep thats it!

The idea is, you do it OVER and OVER and OVER again to sell rare skined stuff and weapon mods. You have to know not to ID everything (you should really test for mods and sell it unided to wisdom seekers if you want to make back your money). And cross your fingers and hope for some rare skinned items.

That's not it, you've got to pick up what comes out of the chest first

But basically, that's it.
