Using the Lava Bow it's possible to kill the first one before the second shows up. If you have a good bow it shouldn't take but a few rounds. He will have a hard time keeping up with you so you may have to backtrack and lure him a bit but keep repeating the process until they are both dead. Just go through the fog gate and fire at him until it gets right up on you then run to the other side of the bridge. Have Thief's Ring and Cling Ring equipped.The second maneater will spawn in, and you should repeat the same strategy. Immediately run up behind him and firestorm again. His AI will become screwed up and he’ll just stand there idle, staring at the fog gate. Dodge all of his attacks and he should either fly away or he’ll turn around and walk towards either fog gate. Then run towards the fire brazier and stand behind it. It will take out over half his health if you are close enough, even if you have low magic.

Once he attacks or starts boosting, get right next to him and cast firestorm. He will either pounce or bite himself with the snake. When you enter the fog gate, immediately run past the first maneater. Make sure you have the thief ring equipped.On NG+ this becomes harder and will require better timing and powerful weapons. As long as you don't let him fly away or get your self surrounded this boss should be easy. Now use that Stamina and destroy the first one. You want the first one near you and have good stamina and your weapons Enchanted if applicable. When he nears 20% health the second Maneater will spawn.Try to go for the tail first to restrict his attacks. A heavy weapon, Enchanted will allow you to make the most of his openings, as long as you don't get greedy. When blocking his lunge (if you can't avoid) do it from an angle, not head-on. Do the opposite if you need time to heal. In here if he lunges he will not fly away. Try to keep your back turned to the fog or the brazier. When you see him get down go to the side and if you can out of his way, since its the lunge attack.

When you see him get up and raising an arm simply walk back and when he punches the ground counter with a single swing.

Rolling will end badly if poorly done so try to block or dodge by running (not sprinting).

Pretty much the same thing as the shield strategy.

Note that this is a one-on-one strategy which assumes that you have taken out the first Maneater using the fog gate glitch.

If he connects he will barely hurt you at all, even on NG+ and beyond. If you want to make the fight easier just cast Warding. A decent shield and sensible stamina management will negate all of his physical attacks. The biggest danger to your health is the environment, so play it safe and only dodge as a last resort.

Rolling around to dodge his attacks is asking for trouble.

It's a matter of weighing your options: If you can reliably interrupt a Maneater as it starts power-boosting, you may prefer having to do that and dodge Soul Arrows now and then rather than run a greater risk of having two Maneaters attack you at the same time. As long as one keeps moving, the Soul Arrow attacks are easily heard and avoided, and a Maneater with its tail cut off will be more eager to mob you and use its melee attacks, including the dreaded pounce.

Note that if you've already caught both Maneaters' attention, it may be to your advantage to try to avoid cutting off their tails.

This will usually cause one to fly away again so you can return to the relative safe-zone and continue wearing them down. If they both land at the same time and charge the central area with the brazier, it's best to run down the stairs for a minute. Many players have died from repeated rushes by both Maneaters. Try not to get it so they will start double attacking you. The strategy only changes in that you should focus on burning down the one you've been damaging because trying to split your damage will just lead to your death.

The real fun comes when he spawns a second Maneater.

The brazier is very helpful in that you can attack almost through the edge of it with some weapons without exposing yourself as much as a direct attack would. You can dodge this reasonably easily, or just keep the central brazier between you and it. It can and will hit you through it with its ground-based lunging attack, so be careful. This brazier will shield you from its melee and magic attacks.

Immediately upon entering the area, run past Maneater to the platform with a large brazier in the middle.

Be careful not to fall or be knocked off the edge because it's very easy to. If you try to melee both at the same time, you will be toast in no time.

For beginners, the trick to successful meleeing is to separate the two Maneaters.

Meleeing the Maneaters requires strategy, skill, and patience.
