(Click on the image, then right click and select "view image" to see full size) This week I bought 75 Three of Coins from Xur, and decided to log the results of using them on a variety of different Ultra bosses. Each time one coin was popped while in orbit, before starting the strike/mission, with at least 20 minutes between coin uses (the one exception being for the Shield Brothers 2nd boss) [b]Interestingly, the results came out to a drop rate of exactly 1 in 5[/b]. Note: There was one occasion where TWO exotic engrams dropped, but for the calculation I have recorded this as a single drop. The coins were all used by my 312 Hunter, who also decoded the engrams (which is why they all came out as 310)
