Mergo's Wet Nurse | Boss Fights Bloodborne Guide

Mergo's Wet Nurse is a living tank.

Attacks

- frontal hit with blades - boss raises two of her many hands above head and then hits them to the ground, giving you a moment for attack; this attack can be also avoided by remaining in front of Mergo's Wet Nurse, perfectly between two blades

- series of hits - boss walks ahead and makes few consecutive swings; despite long reach of attack it is easy to avoid it and get to the back of the enemy, which is a perfect spot to deal few hits

- spreading blades - this attack usually occurs after series of hits, it might deal damage to player standing behind enemy

- a wide swipe from behind - used usually on the right side of the player, very strong and with long reach, easiest way to avoid it is keeping long distance

- sticking knifes - one of attacks that usually ends series, all blades are knocked in one point ahead of boss

- fog - most powerful attack, the boss is creating a violet fog on the arena, then starts walking forward and keeps attacking. Though it is easy to get to the back of Mergo's Wet Nurse (a small chance of being hit, potential small damage), the difficulty is that another enemy shows during the fog, an impostor. Take notice that he usually attacks from your left. The easiest way to avoid this attack is to run around the arena for about one minute, but it will be more effective to combine moving with hitting Mergo's Wet Nurse back.

- disappear - boss disappears for a moment and then shows on the edge of the arena

Combat

Mergo's Wet Nurse is a resistant enemy that attacks mostly in the same, repetitive way - a series of hits, sticking knifes/hit in front, then a wide spread. Learning this pattern will allow you to dodge (usually on the left) and get to enemy back.

Getting to enemy back gives great possibilities for attack.

You should take position at enemy back especially when he is making a series of blade swings and walk ahead not taking too much interest in player. Avoiding her shouldn't be hard then, move back a bit and make two-three dodges under the blades. It will allow you to get to Mergo's Wet Nurse back, where most of attacks won't reach you and you can deal a few of them yourself. Despite that, still watch out for blades and for enemy turning around after she ends her combo.

After each attack there is a while when you can quickly run towards enemy and deal one, two hits.

There is another way to defeat enemy, slightly longer, but safer. If you're not good at getting to Mergo's Wet Nurse back, you can fight while keeping her in front of you. After each of her attacks there is a short moment when you can run towards her and attack her. Just remember about making your weapon longer, deal one, maybe two hits and quickly dodge away. Best effects can be achieved by combining two methods: get to enemy back when it is possible, jump forward and attack after every completed attack when there is no chance for getting to enemy back.

Battle in fog is the hardest part but it gives you opportunity to deal lots of damage.

Things get more difficult when enemy summons fog to the arena. It usually happens after depleting around 1/3 of hit points, fog is usually used 2-3 times (if you deal damage quickly, you will reduce the amount of such attacks by killing boss quicker). Mergo's Wet Nurse at that point starts to walk forward and keeps doing the attack you well know. It creates a great opportunity to get to her back, what you should immediately do. Impostor might give you some trouble, he will attack you from time to time - sadly, his attacks are as deadly and strong as the normal ones, done by main boss. Running around the arena might be solution to them as enemy won't be fast enough to get to you (run opposite to clock direction, enemy shows always on the left, if you will have the border of the arena on the right you will avoid all his attacks), but in that case you will lose a great opportunity to deal lots of damage. A good solution is to combine this tactic by both attacking Mergo's Wet Nurse and making lots of dodges while running around.

This is definitely the hardest part of the battle, if you're stuck in it it will be better to focus on avoiding attacks by running. The fog will disappear after around one minute and the impostor will fade away. The battle will take more time, but if "normal" part of it doesn't give you any trouble in might be a better way to win.
