In level 9 you get to use Arcia. This is basically just a fun level because you get to shoot enemies. Check what happens when you use the dodge technique with Arcia (hold R1 and press X when you move in any direction) This is useful for not getting hit, and you can shoot while performing these moves.
Arrogance Legion
This is the "human shield" Legion. They are best used to create a temporary safe haven. Basically, summon them and keep them in passive mode so that they do not move, but protect. Then, trek out slightly and face your foe. If you find your enemy's numbers are too great, simply fall back to your safe haven and battle them from behind your shields. You may notice that the Arrogance Legion does not exactly pack a whole lot of power in their attack. However, if you wait until they have just a little bit of health remaining, press Force Attack and watch them put the hurt on. Then unsummon them and fight ferociously until you have restored your soul power.
Avoid losing life
Pause game play before the last part of your health disappears. Use a healing item, and you will still have that life.
Be Arcia
Beat the game using normal difficulty.
Blasphemy Legion
Their little floating bombs also turn into convenient little land mines. This legion is best used against Denu, or the metallic and shiny opponents that are impervious to your attacks.
Boxed-up Gates
You will eventually encounter gates with huge metal boxes behind them. Notice that you can lock on to these gates and even attack them, but it does not really do anything. That is because you need to use a Legion's attack to open it. To see which Legion you should use, check the little circle in the gate, and make sure it matches your Legion's symbol.
Change Enemies on Previously Played Levels
Beat the boss on level 10 to unlock "Change Appearance" which changes enemies on replayed levels.
Defeating Giant Trolls
Jump and attack so that you can do a spin slash at its head. That will immobilize it. Keep doing this.
Defeating the Giant Spider Boss
In the cave, have no Legions active so that you can run around. Run up to the Boss and attack its right leg repeatedly. It does not matter if it is the right or left leg, but must be a front leg. After its leg falls to the ground, quickly summon a
Legion (preferably Guilt) and press Force Attack (default Triangle). Attack it for one volley, then press Force Attack again and begin to get away from the Boss. Unsummon your Legion, and look at the Boss while in one of the two small clearings. While facing the Boss, hold R1 and as soon as its first laser is about to hit you, press X and movement Analog-stick Right. While still holding R1, repeat that maneuver once again. Then, repeat by attacking the leg and so on. Note: If the Boss falls from its perch, quickly get near its head and attack the now visible silver orb along by using Triangle with your Legions to assault it.
Defeating the Giant Tree Boss
Find a safe location where the lasers shot by his minions will not hit you. Then, stand there and time the lasers with your Legions and your own attacks so that no health is lost.
Make sure you have the Guilty Legion and the Arrogance Legion equipped for this Boss. When you first get to the Boss, summon Arrogance to protect you. As they absorb the blasts of the cannons, have them return the attack of the cannons for experience. When a couple of cannons are remaining, dismiss the Arrogance Legion. Run to the tree and attack it until it opens up. Then, summon the Guilty Legion. Note: The amount of cannons respawned will increase as the tree gets more damaged -- be careful.
Destroy the final summon
Slash twice and then use the upper cut. Then summon up the 2nd summon and will die.
Easy experience
Find a location where enemies spawn in groups of two or three. Put a Legion on active attack mode and let them kill those same enemies for hours. This works if your Legion is strong enough, but check up every ten to fifteen minutes to make sure your health is still the same. If it has changed, check more frequently to make sure you do not die.
Let your Legions take the kills and do most of your dirty work. You will get double experience. Also, press Force Attack if you are in a tight spot.
For more challenging play, but better experience, when a generator keeps making monsters reappear, just stay there and kill those monsters over and over again, but don't attack the generator.
Go to level 6 and fight all the way to the second stage. Use the Malice and keep using the Force Attack (Triangle). Press it repeatedly after there are no threats around, except for the heads with the spikes that cannot die with conventional attacks. Do this for a while to gain experience.
Experience multiplier
To get the multiplier, get the target result. You can view it by using Select. Try the achieve the maximum time. For health and soul, after defeating the Boss, quickly press Start and use health and soul item to get full. If you get the all targets
closely, you will get something like 3x for the experience multiplier. Note: You can pass the target for special monster, health and soul, but you cannot pass or get less than the level time and Boss time.
Flawed Legion
These are the little midgets with razor fingers. Once you lock-on to a hard to-defeat metal enemy and press Force Attack, they will surprise with how they burrow into your opponents and take their health down a by a considerable
amount. They are by far the worst fighters when left in active mode, which is why they are not recommended for large group fights unless you are in a situation where your attacks are almost worthless. Note: The Flawed Legion's extra abilities and the group's unsummoned special attack are by far the most useful of any legion.

Guilt Legion
When using the Guilt Legion, treat them as your troops and yourself as a general. Command them into attacking targets who pose the largest threat to you by locking on and using Force Attack. If you are in need of protection from an
onslaught, unsummonm then resummon the Legion after putting it into passive mode. Then, when enemies close in, press Force Attack and let your minions do the dirty work.
Hatred Legion
The Hatred Legion is useful when you need some serious back-breaking power. It is best to rely on these Hulk-like legionnaires if the enemy's number is great and you are in need of a little break. They are best left in active mode. However, if you fiddle around with passive mode and target elimination, you can become a ferocious force with this legion.
Leveling up Legions
Make sure to level up one organic-attack Legion and one inorganic-attack Legion (for example, Guilt and Flawed) until stage 9. After that, you can go back and level all of your Legions equally.
Blasphemey and Hatred Legions are by far the hardest Legions to level up. Take out one of your more powerful Legions along if you are using either one of them.
Longer combos
If you want a longer combo try jumping into the air once. When coming down, you will hit your enemy once and when you hit the ground you will start your regular combo. It is still slightly longer.
Malice Legion
This is the crossbow Legion best saved for large numbers of metallic enemies. Sniping is a great option, but consumes Soul Power. When the metallic enemies draw within ten feet of your legion, tap Force Attack repeatedly to "group snipe" them. Keep in mind that this is a great Legion for large numbers, but for other metallic enemies that are powerful as the Hatred legion, (for example, the armor suits on levels 10 and 11), consider using the Flawed Legion.
Play Previously Played Levels
On stage 9 beat the boss and you will get the "Map Selector" which allows you to go to any completed level.
Power-ups
On the stage 11, constantly explore before continuing onward. You will find plenty of power-ups.
Sieg combos
Note: These work only if you have Guilt and Flawed Legions player techs fully leveled. Press Square(5), X. Press X, then X again in that jump, then press X when you land.
Ultimate Legion
This is by far the game's best Legion, yet the most underdeveloped. For example, it teleports to your opponent's blind spot and basically mutilates it. When you use its unsummoned special attack, you can move through a plane of slower time. There is only one legionnaire in this crest. Also, you cannot rely on this Legion to protect. It has a reaction time, and when it attacks it leaves you very vulnerable to your foes.
Note: To get the Ultimate Legion, collect all the Thanatos Chips.
