Ok scrubs, lets get real. If you never had a mirror before and now have a mirror, what do you do?

chuck it in stash with the rest of the stuff without even looking at it

Do something with him that is fun for you in this game, such as:
- upgrade the existing build as much as possible;
- make a crafting project if crafting is interesting to you;
- become a trade master and make five mirrors from one until the end of the league;
- buy some powerful items and keep them as trophies in std. etc

i would keep it. i have 3 mirror shards this league and i'm keeping those too.

Didn't exactly get a mirror but my second uber shaper kill yielded a purity of fire sublime vision which was roughly worth a mirror at the time. Sold it for divines. Bought a MB with it later because why not and the rest will go back to standard with me. Doubt i will ever use it there but who knows.

Solo Self Found so it would just sit in my stash.

more than 15000h of playin' since 2013 and never got any mirror drop .....i stopped thinkin' about it .....

My first drop duped so I got to sell one and keep the other. If it had been just the one I would have kept it.

It would be completely useless item for me. Its going to stash.

Use it in the mirror, rhoa feather and fish recipe.

Playing for 11 years never had one. Never needed it, never will...
'will sell when i drop one ;)
