If you reduce the size of the cluster and the node is the master, what will happen?

I was wondering what actions would be triggered if the cluster master node was shrinking if it was a large numbered node after multiple failures. I don't seem to find any special operations? Will you remove the current master and let it fail over

If the node that shrinks in size is the master role, the cluster will fail over to a new master.
