After returning to Kerber, Žikić continued with his on-stage performance. On May 19, 1984, during the band's open-air concert in Novi Sad, he got second-degree burns while attempting to breathe fire under windy conditions. He continued the concert despite doctor's advice, and later on continued the tour with bandages on his face. After this accident other members forbade Žikić to continue performing the fire-breathing act. In June 1984, Kerber was an opening act for Nightwing concerts in Yugoslavia. In August drummer Zoran Stamenković returned to the band for the summer performances in Greece. In December 1984, Kerber traveled to England to record their second album, Ratne Igre ( War Games). The album was recorded in Saughall, and the producer was once again Gordon Rowley from Nightwing. During their staying in England, Kerber performed in Liverpool and Chester. An English language version of 'Mezimac' entitled 'Get Me Out' was recorded on their concert in Liverpool and included on the album. Part of the album lyrics were written by the lyricist Duško Arsenijević, who continued to work with Kerber on their future releases. In May 1985, only a week after Ratne igre was released, Stamenković went to serve the army and Boban Đorđević replaced him once again. On June 15 of the same year, Balkan, alongside 23 other acts, performed on Red Star Stadium, on the concert which was a part of YU Rock Misija, a Yugoslav contribution to Live Aid. In October 1985, drummer Boban Đorđević was replaced by former Mama Co Co, YU grupa and Leb i Sol member Dragoljub Đuričić. In November Kerber was awarded with Smeli Cvet ( Courageous Flower), an award which was given by League of Communist Youth of Serbia for contribution to rock music. In July 1986, keyboardist Branislav Božinović was, due to his army obligations, temporarily replaced because of army duty by Milorad Džmerković, former member of Slomljena Stakla and Peđa D'Boy band. In 1986, Kerber recorded their third studio album, Seobe ( Migrations), which was produced by Kornelije Kovač. Seobe included numerous hits: 'Hajde da se volimo' ('Let's Make Love'), 'Čovek od meda' ('Man Made of Honey', which featured Riblja Čorba's frontman Bora Đorđević on vocals ), ballads 'Kad ljubav izda' ('When Love Betrays', which featured a quotation from Pero Zubac's poem 'Mostar Rains' ), 'Još samo ovu noć mi daj' ('Give Me just This more Night'), power ballad 'Bolje da sam druge ljubio' ('I Should Have Been Kissing Other Girls') and the haunting ballad 'Seobe'. Following the success of 'Seobe' Kerber performed more than 200 concerts across Yugoslavia.
