and you will encounter the Adramelk Boss.
Defeat the Boss to get the Adramelk summon.

Adrammeleck Esper:
This Esper is located at Athroza Quicksands in Zertinan Caverns.
The place where you fight him has many other monsters that join him.
Do not attempt to fight him until you can routinely 
kill a numerous amount of level 40 monsters at the same time.
Be aware that he is not summoning them.
If you can keep from pushing the battle to areas you have not yet walked on 
you should be able to stop them from springing up from the ground.

6. Enter the No. 1 Cloaca and find the Boss at the low point on the south end.
Save the game before the battle.

Defeating Adrammelech
Have your party at least at level 50.
It is a good idea to save in the land of the Garif; it is the last save spot you will see before this battle.
Go to the farthest area in the Ozmone Plain,
then go down into the underground cavern called the Zertnan Caverns.
Follow the cave though the status-inflicting horses until you reach the third room.
You will know you are there when your mini-map gets fuzzy and there is a sandstorm to your right.
If you have any damage or you need to get back MP,
heal them now for an advantage in the fight.
Remember, there is no save crystal before the fight.
You should have at least three long range weapons equipped.
He is a flying Boss. Also, give the people with long range weapons the best Ice spell possible.
He is a Thunder type, and is weak to Ice. 
One of the most annoying things in this fight is the corpse that appears.
The best strategy is to have two people deal with the corpses and one person hit the Esper.
You can make the "zombie attacks" attack the zombies immediately if you make their Attack Gambit into Foe,
Undead/Attack or Foe, Undead/Curaga to make it so that they attack them.
The person who attacks Adrammelech must have a long range weapon.
It is best if you control the one attacking the Esper. He sometimes uses his Thundaja attack.
It can do a lot of damage and inflict Stop on some of your characters.
Just use a Chronos Tear or a Remedy with Remedy Lore 3 to get rid of it.
If your first team dies it may be a good idea to use some Quickenings to turn the table.
Keep everyone above 60% HP and keep hacking away until the the Esper falls and becomes yours.

Defeating Belias
Have the following party order: Fran, Basche (party leader), Vaan, and Vossler. 
Equip a character with low magic (in this case Basche) with the Nethicite,
as this makes magicks take half damage.
If you have the Evil Slayer, it is very helpful.
Buy a lot of Handkerchiefs (oil remover) from the NPC outside and some Phoenix Downs.
Before entering the altar to Belias, have Fran cast Protect and Shell on everyone.
Next,have Vaan do the healing and Basche do the hitting.
Have Fran cast Water and Slow on Belias.
When Belias is at 40% HP or less, he will cast Firaja (different from Firaga) on you.
This creates an Oil status which makes fire hurt a lot more.
Cure this with the Handkerchiefs,and cast Protect and Shell on Basche.
Keep this up and eventually you can acquire him as your first Esper (summons).

Defeating Cuchulainn
Have your party at least at level 50 and have the Curaja spell.
In the battle, there is a constant HP sap in the area that cannot be stopped in any way.
Have one character use Curaja always, and the other two attack the Esper.
Dispel the Boss immediately, give as many characters as you can a Black Belt,
and stop his Disable attacks. Make one of your characters have Ensna as one the first Gambits.
When Foolbars join the battle, use your strongest Fire-type spell against them.
The Esper likes to use Invert to quickly kill your characters.
It resembles an instant-death spell and in combo with the HP sap, and can kill your people very fast. 
Revive them immediately and use some Quickenings if your first team gets knocked out.

Defeating Famfrit
You will not encounter Famfrit until near the end of the game.
However, you will not meet Famfrit alone.
He is actually summoned by Dr. Cid. After he loses about half of his heath, Dr.
Cid summons him to his aid. Focus all your attacks on the Esper,
because he is invulnerable with him out. He is a Water type; use Oil on him and shoot some Firagas at him.
You can also use your summoning abilities to summon Belias.
If he survives long enough to use his final attack, the Oil will double the damage. 
He already takes double damage from fire attacks, so it will do quadruple damage. 
When he has been defeated, you can then focus on Cid.

Defeating Flowering Cactoid
When you locate Flowering Cactoid, defeat all of the surrounding enemies in the area.
This will leave him without a place to run and hide. Then,defeat him with attacks and magic.
Although you can do this with just Vaan, it is much easier 
if you do this hunt after Penelo has joined the party.

Defeating Garuda
Have three players with the Arcane "Dark" magick. Garuda likes Vossler and will attack him first.
While he does that, command all the members to cast Dark.
When they all cast Dark it will do about 1,890 damage total.
Keep repeating this and Garuda will die in about fifty seconds.

To do a lot of damage to Garuda, cast Reflect on all your characters before the battle.
Then,cast Dark with all of them to the party itself. 
By doing this,Dark will bounce off every character and hit Garuda once each, dealing a lot of damage.

Defeating Hashmal
Start by Dispelling his protections and using Haste and Protect on your party.
Also, use a large chain of Quickenings to lower his HP by some,
but save some MP for later. He likes to use Slow and Disease on you often.
Get rid of it with the proper spell or item. After Hashmal loses three quarters of his HP,
he uses a very powerful attack called Quakeja. To take absolutely no damage from it,
cast Float on your party before he uses it. He will only use it once.
Because he is an Earth type, he is weak to Wind.
Shoot Aero at him as much as possible.
Keep everyone above 50% HP and keep up your Aero to win quickly.

Defeating Mateus
Have your party at least at level 30 (for example,
Vaan as party leader, Basch, and Penelo).
Have both Vaan and Basch to learn Thundara and equip them both with Ice Shield.
Equip Penelo with Storm Spear. Buy at least five Banchus Wine (Berserker).
When the battle begins, have Vaan and Basch immediately cast Thundara to kill all the Ice Ace.
Then, have Basch keep casting Thundara at Mateus and Vaan heal when needed.
Let Penelo keep attacking Mateus. Once its effect wears off, make her berserk again.
It is possible to defeat Mateus in about seven minutes by doing this.

Before the battle,
equip as many Ice Shields to your party as possible.
Get all of your party members to at least level 30.
Also, teach Thundra to as many characters as possible.
When you are prepared, enter the battle.
Immediately get all of the Esper's friends close to her and unleash a chain of Quickenings.
If you are lucky they will completely kill her little friends.
If not, take out your reserve party (or just use some Ethers and/or Exthers to get back MP) 
and use your Thundra spell to finish them.
The only attack of Mateus' that you really have to worry about is her Blizzaja attack,
unless you equipped the Ice Shield, then it will not do too much damage.
Also an ability she has may cause Sap, but you can get rid of it using Regen.
Keep everyone above the halfway mark and do not cast any spells on her.
The Esper has Reflect on herself, meaning that Thundra will be bounced back at the party.
Keep attacking and healing to defeat her.

Defeating Rockeater
Use a lot of wind magic (Aero) and attack him physically and he should go down fairly quickly.
To defeat him very fast, make sure you are at full MP and summon an Esper.
He will help greatly in battle.

Defeating Shemhazai
This Esper has a very annoying habit of Silencing your party.
Make sure everyone has an Anti-Silence Gambit before fighting.
When the battle begins, immediately Dispel the Boss to remove her Haste.
Start a chain of Quickenings to deal a good amount of damage quickly.
After she uses her Mana Spring ability she is weak to an element,
but absorbs all the rest. Only use spells on her if they are non-elementel.
The Esper also casts Syphon, stealing some of your MP, but it is not too much to worry about.
Keep attacking and healing until you defeat her.

Defeating Thextera
Note: You must be at least level 4.
Go to the Sandsea and look at the board that contains information for all the hunts.
After choosing the "Thextera" hunt, talk to Gatsly,
who should be east of the board.
He should be sitting on the floor.
After talking to him, go into the Westersands.
Do not look for Thextera just yet.
First, defeat all the wolves in the area.
If you fight Thextera without clearing out the wolves first,
he will call for backup, and the wolves you have not defeated will come to his aid.
After all the wolves have been killed, fight Thextera; he should have two wolves by his side.
Try to take them out first by luring them away from Thextera.
After they are finished, you will only have Thextera to fight.
Make sure you have a decent amount of potions 
before you fight him -- his fang attack does about 120 damage.

Defeating Tiamat
When fighting Tiamat in the Henne Mines,
he does an Aero attack on all of your party members which can cause a lot of damage.
To prevent this, cast Reflect on all of your party members before the fight.
Whenever he uses Aero, it will bounce back to Tiamat.
This will cause it to recover a little HP, but you will not receive any damage from that attack.

Defeating Vossler
Start by killing the three soldiers around him.
Once they are dead, focus on Vossler. 
He will be easy, as his attacks do not inflict too much damage; heal when necessary.
After he is down to a quarter of his HP, he will use a move called Enrage,
which basically makes him go crazy and attack much quicker.
He can kill your characters very quickly this way.
Summon your newly acquired Esper, Belias. Belias takes full MP to summon.
You may want to teach him to a character that is not in your active party.
After Belias is summoned, have the character 
that summoned him step back so that Vossler will target Belias.
If you summoned Belias after Vossler used Enrage, Belias will kill him.
Heal Belias when necessary.

Defeating Zalera
Have your party at level 56; no more, no less.
Save at Terminus 7 Adjunct before the fight.
There are a few things in this battle that make it more difficult.
First of all, there is a 5:00 minute timer.
If you do not defeat Zalera before the time runs out, you must start again.
You also cannot use Espers when there are undead in the area.
Finally, he can cast status effects on you based on your level; 2-5 are the ones he can do so on,
and he can also use status effects on you if you have a prime number for a level.
To begin the fight, dispel the Boss. If there are undead in the area,
get everyone to attack them. When his HP starts to get low, he will start to cast Sleepga,
Stop, and Death, no matter what level you are near.
Near the end, use a Quickening chain to finish this long fight and get the Esper.

Defeating Zeromus
Have your party at least at level 50.
You can defeat Zeromus as soon as you complete the Stilshrine of Miriam dungeon 
and get through the scenes at Mt. Bur-Omisace afterwards. 
After defeating the Judge, exit the map where you killed him 
and speak to the Acolyte somewhere on the map to receive a Stone Of Condemner.
Stock up on healing items as you cannot use magic during the battle with Zeromus.
At the southern end of the Ward of Measure, touch the Waystone.
You will be given an option to use the Stone Of Condemner; use it.
You will be transported to the Throne Of Veiled Gods.
Before opening the door to Zeromus, place positive status effects on your characters 
and tweak your Gambits to use items instead of magic to heal.
You may want to do this later in the game 
when you have more powerful equipment and are at a higher level.

Have your party at least at level 50.
After defeating Judge Bergan,
you will automatically be teleported directly outside the area.
In front of you will be an Acolyte pacing back and forth.
Talk to him and he will ask you to find a "greater power" in the Stilshrine of Miriam,
and give you a Stone of the Condemner.
Teleport to the Shrine and go inside.
Go to the Way Stone at the south end of the room you are in.
You may have to fight two undead foes at the Way Stone,
but if you can defeat them you can defeat the Esper.
If you use the Way Stone, it will stop and say that the stone is having a reaction.
Use it to be transferred to the room before the Esper.
All Magicks are disabled in this battle.
Before the battle, change all healing Magicks to items 
because you cannot use Dispel on him; you cannot get rid of his status Help.
The Boss is also not alone.
He is joined by a large army of Dark Lords.
If you have Holy Motes, use them.
After defeating about thirty Dark Lords, they will stop appearing.
When he is very low on heath (about 30%), perform a Quickening Chain.
Keep everyone above 50% HP, justory line)

Exodus Esper
This Esper becomes available after you battle Cid in Draklor Laboratories.
Go to the Babbleing Vale in the Moshphoran Highwastes.
One of the villagers there by one of the shires will tell you that the shrines have started working,
but he is not sure what they do.
Activate the three eastern wind ones first (northeastern,
eastern,
and southeastern).
You can only activate three at a time.
Look at your map and you will see three new marks on it that indicate bridges 
have formed to areas you could not reach previously.
Next move east to the Rays of Ashen Light section and find the Chocobo in the northern section.
Feed him a Gyshal Green and ride him through the newly opened area 
to the end where you will see a path leading onward blocked by bushes that only a Chocobo can cross.
This will take you to the Sky Reach Ridge section on the western side of the Vale.
From here you can enter the Vale and activate a shrine that was out of reach before.
Once you have gold man,
but do not leave this area yet.
After a bit, go back to the same place and tken sands area.
Get three and return. Then later in the game go back.
Talk to her to learn that the patient has made a full recovery and is behind her house.
He is actually a traveler hunter that will give you the item you need to get Zalera.
It is called the "Barheim Key".
Use it on the "Weather-beaten door" in the area that is left of the village going south.
Make your way to Terminus 7 and just keep going through there.
Soon you find there is no way to get to the next bridge.
Just look for a mine cart that is on the right-hand side and press X.
There will be what seems to be an endless army of the undead on your way.
Save at Terminus 7 Adjunct before the fight.
Defeat the Boss to get the Zalera Esper.

Zodiac Esper
Get ten or more Espers and finish the Mindflare Mob Hunt mission (rank B).
Next, talk to Feng Shui Master Yuggil in Jaharago.
Then, go to Henne Mines to fight the Zodiac Boss.
Defeat the Boss to get the Zodiac Esper.

Zodiac Spear
Open all treasure chests in the game except the following:

1. Treasure chest in Lowtown, outside of Old Dylan's place.

2. When sneaking into the palace (before getting the Goddess Tear),
there are several chests in the Cellar. Do not open the two chests in the southeast corner.

3. All treasure chests in the Confiscatory 
(the place where you get your weapons and armor back after being captured).

4. In the Phon Coast, later in the game, 
there is an island with sixteen chests all near each other.
The fourth chest among all sixteen must not be opened,
so it is best not to open any of them.
They only contain Gil.

Then, go to the Necrohol of Nabudis to find the most powerful weapon in the game,
the Zodiac Spear. It has a +150 Attack with +8 Evasion.

Zodiac Spear Insurance
If you plan on getting your hand on this,
most powerful weapon in the game,
DO NOT open the barrel that sit directly across from Dalan's door.
Apparently it's linked to four other chests in the game that must remain closed 
until you have the opportunity to acquire it in Nabudis.

Zodiac summon
Get ten or more Espers and finish the Mindflare Mob Hunt mission (rank B).
Next, talk to Feng Shui Master Yuggil in Jaharago.
Then, go to Henne Mines to fight the Zodiac Boss.
Defeat the Boss to get the Zodiac summon.
