I have 10 characters that can reach all 12 Treasures and an 11th that can reach 10 of the 12. All 10 of the characters that can reach all 12 spots get purples and roughly 50% of the gold from the initial opening. From observation, I make the assumption that each character will receive 20-24 gold items, then they get nothing but purple.
I came to that number from 2 character sets. First was the characters that had access to all 12 spots when they were introduced. Second were characters that could only reach some of the spots at introduction. The first set of characters got a gold item on ALL of the first 12 chests they opened. The second time they opened them, I got ALMOST all gold items, but a couple got 1-2 purples. The big indication for me was my Ritualist. I rarely used her at the time the chests came out. By the time she got her first chest I was already getting purples on my main characters. She opened only 4 chests her first month. Second month she had access to 9 chests. Not until the END of her thirst month did she see purples appear, and that was when she was getting all 12 spots. 4+9+12 = 25 She got golds on all butthe last 2 or 3 spots, so she received 22-23 golds total.
And if you are wondering, I include rubies/gems as a gold item. At roughly the point where the purples show up, the gold hit bottom as well - some characters get as little as 30% the initial amount.
