Lost Relic Pass Registry/Pre-v15.0

Introduction
"Lost Relic Pass Registry" is a new feature introduced in v12.4 and allows you to buy 30 days access to stages using coins. A stage consists of one or more battles and each purchase will give you 1 "Challenge Chance" to one of the battles of that stage.

Purchase Stages
There are two ways to purchase a Lost Relic Stage:
 * 1) Navigate to "Shop -> Lost Relic Pass Registry"
 * 2) On the main screen, scroll down and tap the Airship (note that the airship is not present in-game yet)

The next screen will show an overview of all stages that are currently available, how many "Floors" (battles) a stage consists of, how many coins it will cost and how many times you can purchase the stage (usually this will be unlimited).

To purchase a stage you tab on the stage you want to purchase and either select "Single Purchase", which gives you 1 "Challenge Chance", or "Purchase 5 challenge chances", which will cost 5 times as much as a single purchase.

Access Stages
Purchased stages can be access in the Lost Relic and will show the expiry date and how many "Challenge Chances" you have left for that stage.
