Wow. Just by looking at these posts it seems as if the Shiny Chances have increased! Apparently if you tip people (like bards, waiters, etc) the maximum amount of money then your Shiny Chances will increase. I'd love it if this was confirmed but only seems like a rumor thus far.
Hmmmm I might take 10 photo's then and tip maximum ;p
Still no luck in finding shinies... I just started with the looker missions, is there a page about this yet?
