I did thurg helm at 19 on my human cleric. You need kindly. Going from apprehensive to kindly takes about 170 kills in WL with faction groups. Thats the quickest. With faction song, you may need alot less. Go check in thurg first to determine how many kills in WL you need. Every giants gives about +5 thurg faction (+1 CoV only). Faction chart is there :
