This mark loves to cast Petrify so make absolutely sure to have an Auto-Soft setup. Lamont is helpful for this battle so consider having him around. This ugly Cockatrice comes with three Chickatrice pals. They'll complicate things if you let them overwhelm you. Take them out as soon as possible - a Quickening will help with this.

You'll want range weapons and a full time healer for this battle. Keep the party spread out and don't get them underfoot of the huge tortoise. If any undead spawn while you're fighting take them out fast - Quickening if you have to.

After you find the mark you can switch out the girls for other party members if you choose. The mark shows up with Shell, Protect, Haste, and Bravery - if you've got Dispel use it first. This guy can throw Blind, Confuse, Poison, and Sap at you so gambit accordingly. You'll absolutely want to Blind the mark to limit his heavy physical attacks. If you have Fira then that's your best attack (if you can use Shear then it's even better). If you don't then put in some heavy hitters. Keep the party spread out to avoid area spells.

Once you've made the bridge and cross over you'll be met by Bansat who is going to fight with you. To get the mark to appear the rain must be at its strongest. Otherwise the area will be filled with Lvl. 37 Tortoises. Pop in and out until the weather's right. If you've got Dispel get rid of the mark's defensive statuses. Hit it with Slow, Immobilize, Blind, and Silence. With those in place taking it down isn't too hard. Fire spells and Ranged weapons are your best attacks. Make sure to retrieve the Feather of the Flock from the urn in this location. You'll need it for the Cockatrice Retrieval sidequest.

Monid will be your companion on this fight. Make sure to come equipped with Bubble on everyone and have a well set-up healer with Curaga. This mark is going to run back and forth over the ENTIRE area. Don't chase it. It will always come back to you eventually. Blind and Silence the mark if you can but it often uses White Wind to protect against status effects. When the mark gets to 1/4 life things get tricky. It's going to put up a Physical Paling. Not only that but it will only be weak to one magical element and that element changes after each time it's hit. It also starts to use a high damage area attack. Ideally, before it gets to this point you should Quicken it to death before the Paling goes up. If that fails then you need patience and hopefully some non-elemental magic to knock it out.

When you reach this mark it will be accompanied by extra Mantises. You need to kill these immediately. This mark uses Canibalize to raise its level. If it Canibalizes more than one Mantis you need to run and come back later. Quicken and Concurrence to get rid of the extras. Next you need to keep it pinned in the alcove so it doesn't find more snacks. Set up your toughest fighter with a high level shield and a Jade Collar. Decoy that fighter and put them in front of the mark. Position your other fighter (also high defense) on the opposite side of the mark so that only the Decoy takes the mark's Flatten attack. Keep your healer as far away as possible and still be able to help. DO NOT use your healer for Quickenings. Rotate in another fighter for this purpose. Your healer needs their magic for you to survive. It's a good idea to have someone with a Black Belt to prevent Disable. After the battle one of the kids tells you about a key they dropped. You'll find it later next to the Fallen Bhujerban in the Phon Coast. You'll need this Site 11 Key to get to future marks in these mines.

Stock up on Chronos Tears and Remedies before this battle and have them set to gambits. You'll want someone immune to Stop because it uses Time Requiem a lot. It also uses Putrid Breath which causes Disable, Sleep, Petrify, Confuse, Disease, Slow, Immobilize, Blind, Poison, and Oil. Keep your party spread out so they don't all get hit with this at once. Surviving the statuses are the biggest challenge here. You'll also need to Dispel the mark right away to get rid of Haste, Shell, Protect, Reflect, Regen, Bravery, and Faith. Don't bother casting status attacks on the mark because every time it uses Putrid Breath they're all cleared. When the mark's life gets low it uses Growing Threat to double its level. Quicken it to death at this point. Also, this mark absorbs Dark so don't have any Ninja Swords out.
