Luck
 

So, what does Luck increase? Diamonds on a drop? Blessing faster?
I've heard many of things, but which are true!
Can someone be specific and explain where they got this information from. Thanks

I think dias drops is one, blessing is another. not sure on the rest

actually I seem to get less diamonds with more luck. The only thing luck seems to increase is blessing speed.

Luck also increases your chance of alchemy
