Mentioned in the bilingual Greek and Church Slavonic inscription on the niche of the prothesis in the Cave Church of the Monastery of the Holy Transfiguration of Christ (Sveti Spas) in Zrze, which is dated in the year 1368/1369. Probably the painter of the church. The devotional inscription does not clearly indicate the role of Dobroslavь in connection with the church. He could be the painter of the painted decoration of the church, but also a person, who commisioned or sponsored the frescoes (ΔΕΗΣΗΣ ΤΟΝ ΔΟΥΛΟΥ ΤΟΥ ΘΥ ΔΡΑΓΟΣΛΑΒΟΥ ΚΕ ΔΟΠΡΟΣΛΑΒΟΥ and PROSTI BOŽE DRAGOSLAVA I DOBROSLAVA).
