I hav already Barbarossa with skill lv 3 [ i hav gold in bag but for som resom the skill lv 4 missing.] Normal i culd buy higher lv skills for her but , i can't. Just bicose all skills lv 4 missing on skill list. And there is a nader problem with Barbarossa. Somtimes if im inside dungeon she just disipird. She do not diee from dmg [ haevwer im allways full buffed] just if im far away [ just bicose i try to lure 6- 7 monster at once and kill them using mass skill.]
