Barnim is known for his engagement in piracy. He erected a fort and a port for this purpose in Ahrenshoop, which was destroyed by Rostock in 1395. He allowed the Victual Brothers, a pirate organization assaulting vessels of the Hanseatic League in the Baltic Sea, to use the Peene river as a winter refuge and the Bay of Greifswald as a basis. In 1398, he signed a treaty with the Teutonic Knights not to further support the Victual Brothers (then also "Likedeelers"), but kept on engaging in piracy himself. On one of his expeditions, he was caught by the Hanseatic League in Kopenhagen's port. From 1400-1403, he aided the dukes of Mecklenburg-Werle in their campaigns against Lübeck. Barnim himself was wounded once at Lübeck's gates.^[1]

In 1405, Barnim died of the Black Death. To avoid this fate, he went on a pilgrimage to Kenz near Barth, but died on his way in Pütnitz (a part of today's Ribnitz-Damgarten) on 23 September 1405. He was buried in Kenz, where a large wooden statue resembling Barnim was furnished.^[1]
