Sadly the only way to counter the life drain is to upgrade skill, gears, gems, and level cause all of the the skill of a berserker has life drain in it. *but you can also equip "healing" gear which can restore your HP when it is near low percent that would help you *also in inscription has a "rejuvenation" when you refine 3 of it to activate the skill which restores your HP too. Hope this help ☺️
Have you tried clicking all of the bottle beside her? If i remember correctly it won't show unless you click those bottles beside her, and she shows an orange diamond on her head, hope this would help ☺️☺️
