Adding up all the golds from everyone on my current friends list, I've received 1243 golds, and no Inner Pieces yet. I'm curious if I'm just having really bad luck or if her odds are under 1 in 1000.
I asked about IP odds during in game chat complaining that I had opened over 600+ gold gifts with no luck, Cell alluded that the percent for IP was really low, I asked less than getting a Dia from a relic...I got no response...I took that as a "yes". After finally reaching approx. 900 gold gifts, RNG smiled upon me yesterday. I'd say .1% is a strong possibility.
