I'm an Amazon level 41 and hired Hollis (level 40) and have also a Valkirie. I'm using a bow (freezing arrow is upgraded to 5 and immolation to 8). Hollis have a strong armor (302 def) and helm (64 def) and use a sword that cause 125 lightning damage. Only 2 or 3 hits from Baal are necessary to kill my mercenary... Anyone have some suggestions?
