Salvage legendaries?!

[ypad]

I'm highly curious about this option. Probably not many people use it. But I wonder what it does exactly. Does it just salvage newly found legendaries to forgotten souls? Does it touch existing legendaries at all? I'm really afraid if it doesn't work perfectly, and accidentally salvage my good stuff.

I really want to use it, as I'm pretty much have all the gears I want thanks to botexploit, but I just need more forgotten souls to re-roll to good stats.

Titanium, please help me clarify! Thanks!
