You convert as soon as it becomes available then pray.

The first reformed center of reformation spawns randomly by the event The Reformation Branches Out[eu4.paradoxwikis.com]. But I think the next two nations which convert and which have a province which is eligible for a center of reformation, will get one. A province is eligible if it fulfills all the following conditions:
it is in Europe; it is Catholic, Protestant, or Reformed; it is not Rome; it is connected by land and straits to the capital; it is not already a center of reformation; it is not a one-province island with no straits; it is not currently expelling minorities; it has at least 10 development; it does not neighbour another center of reformation; it is not in the same area as a center of reformation of the same religion; its climate is not Arctic, Arid, or Tropical; and its terrain is not Coastline, Coastal Desert, Steppe, Desert, or Glacier.
