The Church

This is called the holy church, and should not be confused with the holey church.

Unlike other shops (excepting the Bank), you can only buy one item offered at the church for each visit, or you can turn in your Relic.

Items
Additionally, you can bring a Relic to the Church in exchange for 1 rupee per turn. However, giving them a Relic means you can't buy an item during that visit. You can give the Church up to 5 Relics before they tell you that they've had enough. They will accept additional Relics, but won't reward you for them.
