Bloodborne Mergo‘s Wet Nurse - waste of skin - no blood vials

Mergo's Wet Nurse slain at level 4 without the aid of blood vials. Always thought this was a boring fight, dodge to the left and stay behind, at level 4 with no blood vials you can afford to make 1 or 2 mistakes but some attacks will one shot or combo kill you from full. The weapon used is a +10 saw cleaver (getting a blood rock without blood vials or sedatives was fun) with 3 cursed blood gems (physical attack up 18, 19 & 19.8 each with irrelevant negative effects). I also used the +8 flame sprayer to get in some damage as stamina recovered. lock on and strafe left against every attack to get behind her, dodge backwards against some combos. once behind her pile on hits. Once she summoned the purple haze I went for the safer option and ran around the area until it passed. Killing the Wet Nurse means the game minimally completed, but leaving the run there would be no fun. I still haven't used a buffing consumable.
