Draw weapon during a jump attack - During your jump attack, hold L2 then select "Berserk" Release L2 and hold R1. Kain should draw his weapon and hit them with it.
Sneaking up on enemies - Hold L2 during game play to be able to creep up on enemies and attack them. Be careful, as at times enemies may be blocking because they may have seen you. This does work on end Bosses.
Rage attacks - Get your rage bar full. To do this you must block a number of attacks. When your rage bar is full, press R1 + Circle to do the rage attack. It works with Fury, Berserk, etc.
Strong attacks - Pick up the an enemy by pressing R1 + Triangle when close. Press Square(2) to do a light attack. After doing this, press the Analog-stick Up then press Square, which does a large amount of damage to the enemy.
Instant death attack - To do an instant death attack, you must have mist in the area of the person. Enter the mist using your dark skill ability "Mist", then sneak up behind them. A skull will appear. Use this time to attack and you will cause instant death to the enemy. Note: If you run into the front of the person, they will immediately attack.
To do an instant kill you must have either the thick sword or the sword ax weapon equipped. Block until an enemy rests, then go to them and press R1 + Triangle to pick them up. Depending on the enemy, you should be able to cut their head off. This will not work on heavily armored warriors. Press Forward + Square to make Kain chop the head off.
Easy health - Immediately after clearing a checkpoint, if you are low on health, reload the game. You will be back exactly where you just were, except your health meter is now completely full.
Hint: Raising Kain's lore - When you encounter a save point, avoid it. Instead, first kill all the enemies ahead. After your satisfied with the amount of enemies you have killed, backtrack to the save point that was skipped and hit it. The game records your current lore level at this point. Next, after the save point is hit, kill yourself. Therefore when you regenerate at the save point, you will have the same amount of lore. All the enemies that you already killed are back. Kill them again and get even more lore. The Relic Boxes also work in the same way.
Draw weapon during a jump attack - During your jump attack, hold L2 then select "Berserk" Release L2 and hold R1. Kain should draw his weapon and hit them with it.
Defeating Faustus:
At first, you are in a small circle room with two doors. All you have to do
is face the Boss and hold R1 + L1 (Attack and Block). Wait for him to attack.
He has four different types. In the first, he does a five or six hit combo.
In the second, he can punch, then kick. In the third, he will just kick. In
the fourth, he jumps back with a red glow and lunges forward. When he uses his
first type of attack, wait until he punches a third time, then release your
block and attack. Repeat this about five times to continue. In the next room
you must use the mist form to sneak up to the furnace and burn him. To do this,
you must first find the two furnaces with fog in front of them. They are on
opposing sides. When you first enter the room, one is to the left and the other
is to the right. Run around until he jumps to one of the two, then sneak to
the corner and turn mist on. Slowly walk to the switch and fry him. Finally,
he will jump around and lunge at you. Just run around until he lunges. This
will cause him to eventually fall. Run up to him and use a combo. This must
be done about three or four times in order to defeat him.
Keep blocking and sidestepping his attacks while finding open spots for attack until you get about one quarter of his life down. Then, he will run off and enter a room will large heaters and mist around them. When Faustus jumps on to a heater, proceed towards the beginning of the mist trail that leads to the heater and pull the switch to hurt him. Keep repeating this procedure until he jumps up on to a chain, then run to a corner of the room and stay there until Fautus jumps down . He will now try to jump and kick you from far away. If you sidestep his attack, he will hit the wall and will be vulnerable for a few seconds. Keep repeating this until he is dead.
The easiest way to defeat Faustus is to block until your Fury bar glows and hit him with that. Dodge every time you see him try to use a glyph attack. It only takes two Fury hits to get him to go to the furnace room. Load up the Mist glyph and head to a steam spot immediately. You should be able to turn on the furnaces without taking too much damage running from steam spot to steam spot. Once he gets burned and starts running around the rafters, just run around the edges of the room until you hear him drop down. Try to be near a corner or wall. Wait for him to jump at you, then jump or dodge his attack. Once he hits the wall, he will be stunned. You can hit him with a good combo before he jumps back up to the rafters. Repeat this two or three times and he will die quickly.
Defeating Magnus:
Magnus is fairly simple to defeat. When he is standing in the middle of the
giant fountain that is surrounded by statues, run and hide behind the closest
one. He will try to burn you, but will hit the statue. Jump out and shoot him
with Telekinesis very quickly. Once he falls into the water, run behind the
next statue until he tries to burn you again and repeat the process until he
leaves. It should only take three times. In the next room you will see giant
statues holding scythes. Magnus cannot burn you anymore, but he will charge
into you. Do not bother hitting him. It does not do any good. Get in front of
one of these statues and get him to charge you. When he does, dodge him and
he will run into the scythe, breaking it. Once it breaks, you will see a glowing
telekinetic switch. Jump onto one of the boulders or platforms so Magnus cannot
get you, and shoot the switch. The statue will open its arms. Do that to all
of the statues and the gigantic statue in the middle of the room will be put
back together. Get Magnus to charge into the base of the weapon that the statue
is holding the same way as before. When it breaks, make him charge into the
base until the statue falls and crushes him. Just stand next to it and shoot
Magnus with Telekinesis. That should make him charge you.
Defeating Marcus:
You will fight Marcus in a cathedral, on the bottom floor first. On the left
and right sides of the room are switches, one on each side. These switches activate
bells which disrupt Marcus' concentration and leave him vulnerable for a short
time. Hit one switch, then run to the other switch, hitting Marcus on the way.
Continue this until his "puppets" disable the bells. Go up to the
second floor. Marcus will just run around until you kill him. Use the jump ability
to alternate between sides, hitting him on the way. Once he dies, you obtain
the Charm ability.
Just hit the bell switches and hit him when he is stunned. When his puppets disable the bell, you can still ring it by jumping into it. He is easier to locate that way. Then, just run around killing enemies while hacking up Marcus, occasionally ringing the bell. You can avoid the puppets altogether, but you will want to build up your Lore bar as much as possible.
Defeating the Sarafan Lord:
When the battle starts, the most important thing to do is to locate him. When
you do, go to the platform across from him so that there is a walkway between
you. When he fires the energy orbs, jump above the first one and stay down on
the second. Then, jump again on the third. When he is over you will have seconds
to use your Telekenisis on him. When you use it, immediately switch over to
jump and knock him off the ledge. You cannot be too close to him when you try
to jump or he will teleport away. When he has the Soul Reaver out, switch over
to Immolate. He only has one set of attacks. He hits you five times, then uses
the magic red sword. Block his five attacks, jump back from the sword, and use
Immolate on him. This is the only way to hurt him here. Do this three times
to continue. When you get the Soul Reaver, he still has the same attack pattern
(five hits then the magic punch). Block the five hits and jump straight up in
the air to dodge the red hit. When you get down, immediately use the Soul Reaver.
You can only hit him one time per round of attack. It will be awhile before
you can defeat him.
When Kain has the Soul Reaver and the Sarafan Lord does the five hits, dodge the magic hammer blow. Then, grab the Sarafan Lord and thrust the Soul Reaver through his chest. You will defeat him in less than a quarter of the time it would take with one hit on each turn.
Once you have obtained the Soul Reaver, build up your special power and use the berserk attack. It will kill him within two hits.
Defeating Sebastian:
When the battle starts, run the opposite way of the mist shooting out of the
grates. Jump over when needed. Sebastian will not jump, thus burning himself.
In his second phase, you must be directly behind one of the mists and follow
it around until it stops. When he grabs onto the wall, put the purple portal
object between you and him. He will run directly into it. Do this three times
to continue. In his third phase, he will try to destroy the stone. Jump up there
so he gets off and charm the peasant in the room to unload all of the mist on
the ground. His fourth phase is just a fist fight until the finish.
Allow Sebastian to kill you once. Then, allow the game to idle and watch the "steam" appear and kill Sebastian.
