The soul relic drops souls every so often. This happens regardless of where it is located.

My Suggestion:

Soul Relic only drops souls if it is placed into a halls treasure room.

And instead of just dropping it on the ground, it deposits it into the account of the church.

And Maybe add another slot on the church info Relic , which shows how many deposited by the Relic.

Just a rough suggestion atm, I am sure it can be improved on.
