Question
Where can I find my rewards?
Answer
The rewards are stored in the Vault. Open the Bank - Chest icon in the top right corner of the screen - and select the Vault tab.
All the Scrolls are studied right upon claiming them. Important note: if you find a Scroll that you have studied before, you will receive XP for studying it again.
N.B. When you get a Reward Chest for gaining of a certain number of Quest Points, it opens as soon as you enter the Quests menu. At that, you can see the window with congrats and items added to your Vault a moment earlier.
