Thanks for taking a look. Sorry if some of these are crap, I'm rather new to the game and pricing.

Scythe 15-20k...
Chaos axe ignoreeee
brass,salv mods, merch..
chalise.. merch

agree with olle except on chaos axe its more like 50k-70k

chaos axe 70-80k +5 is more rare than 15^50 on this particular skin
Yes i edited thought i saw something else cause it was late

Can someone explain the logic on the Chaos Axe to me, how it could be at such a wide range of estimates?
