Yesterday I was very disappointed in my daily reward (1 Credit) in the Bronze 1 level. today, I decided to level up to Silver 3 level and rented a handful of Summoners, Alphas, and Legendaries.
Alas, It paid out (I think) I received a Vinari Bonessmith worth $1.18 in today's value. I guess we just have to level up to receive more rewarding chests.
