First level cap was 16. 21 came fairly quickly though.

First plat chests were things like Founder's Armor Chest, Founder's Helmet Chest, Founder's Jewelry Chest, Founder's Mystery Chest, Founder's Weapons Chest, Premium Jewelry Chest. There was also a Leprechaun bundle. I think that came a bit later.

I think Story Tokens you had to get 1 at at time.
