Someone asked me to do this so here it is.
PSA: Rarities Only Drop From Boxes
Except for the part where I'm 99% positive that I got a Fire Crystal after I killed an enemy with no Treasure Boxes around...
Invite all your boxes friends to the party so we can farm rarities
No Dragon, you will become insane and probably kill yourself through the thoughts of 1000 sandviches
Only I have Ventured 3 inches into Lugi's Brain without Dieing.
I'm pretty sure I got an orb of alchemy after defeating a mega-lichen on one of the later t3 missions.
Not positive.

I spent few minutes for that.
Ooh I like that, someone verify it and put it on the wiki ir something.
Yeah, sorry but that isn't true. At least not for Elite difficulty. You can't get shining crystals on D22. You can only get radiant. Sorry!
At once i found 4* crystals on 22 depth, but it is rare moment, like 3 sparks from one box.
On what difficulty though? I have never seen a 4* crystal drop in D22 on Elite.
They might have a find rate curve that basically causes the find rate of 5* to drop off exponentially the earlier in tier 3 you are.
Cool beans.
So what should we do with that information, throw a party?
