On 5 May 1341, he was elected Bishop of Wrocław, but due to the opposition of the Archbishop of Gniezno, Janisław, he had to personally go to Avignon for Papal approval, which was confirmed on 28 January 1342.

He introduced the feast of St. Jadwiga and also had audiences with Emperor Charles IV of Luxembourg and King Casimir III the Great.

In 1348, he purchased the castle of Jánský vrch from Bolko II of Świdnica, and turned it into the palace of the prince-bishops of Wrocław.

He died on the night of 5-6 April 1376 in Otmuchów,[2] and was buried in the chapel of St. Mary's Church, Wrocław Cathedral, in a marble sarcophagus.
