In The World That Never Was when at the altar of naught before you go in the big door make
sure all AP boosts, magic boosts, strength boosts, and defense boosts to sora and make
sure all your accessories and armor are equipped to sora and riku because they will fight
the final boss without goofy or donald(give any accessories and armor you want for what
you want raised the same with the abilities) (make sure for one of riku's abilities pick
the one limit attack called session which sora and riku can perform uses all mp it is
useful later) you only need to be between Lvl 39-42 it doesn't matter what keyblade but I
used oblivion(black keyblade sorry if I spelled wrong) equip to sora 3 hi-potions 1 ether
and 1 elixir I did not need to use the magic spell to cure a lot you now save and go
through the door(do not try to use your 3 hi-potions 1 ether and 1 elixir until I say now
for the real final boss if low on health use your cure spell)when you go in buildings will
start to come out of the ground toward you press the triangle button when it says and you
will slice through them then continue you will step on a platform and be raised up press
triangle when it says and keep hitting it over and over to destroy buildings flying
towards you then after that you fly off to the next area you should then see what looks
like a giant hole their are 2 of them all you do is it the heartless at least once to send
them to the hole to damage it at a certain point it will tell you to use stunt dodge(press
triangle button)to avoid the giant beam that comes out them you move to the second one
repeat what you did to the first one at a point they will explode so use stunt dodge then
when both are destroyed you move on you are in a whitish colored room where you target
thing with mark on it, it is bigger than you and it does not fight back(I don't know what
it is called) keep hitting it to destroy it  at certain points a force field covers it and
you have to defeat the nobodies and watch for falling objects to get rid of the force
field when you destroy it you have to press the triangle button to carry on in the next
area in the next area you go against a guy sitting in a chair he has 3 attacks his
swinging sword which sends you backwards, a force field(don't touch it until fully gone it
will take health away and send you backwards), and he will summon the weapons of the other
organization 13 members to beat him faster use sora and riku's limit attack session uses
all mp, after you beat him a story part will happen then after that you will be in the
space ship(not gummi and from here on out it's just you and riku)you have 3 attacks laser
for destroying the heartless that look like clocks sora using his keyblade(ignore) and
drain which drains the energy of the pink lasers sent at you. All you do is drain energy
until you can use megalaser (triangle button) to destroy parts of the dragon at certain
times the dragon will send rockets and white colored beams just go around the screen
clockwise direction to hopefully miss the attacks repeat all of this until you beat him
then you go against the guy in the chair again nothing is different except for a few
things one if you press the jump button over and over you go up higher and higher also
when anywhere in the air press the square button to glide, the guy has more health, at
points when he hits you with his sword you will go all the back where he will send
buildings and red lasers at you dodge and glide to one of the non moving buildings press
triangle at it to send riku and the building toward the dragon keep pressing triangle
button to get rid of his barrier then the dragon sends white beams at you either keep
jumping up or just fall(be careful how low you get I don't know if you die if you get to
low) this happens 2-3 times after that get to the guy sitting in the chair and keep
attacking him remember to use sora and riku's limit attack session do all of this to beat
him. Now for the real final boss you are in a white room quickly press triangle button
over and over to dodge the onslaught of multiple attacks (note: when you do this you go
pretty high also he does this only once) when he is done you fall to the ground his
attacks are his red looking lightsabers, a big sphere he puts above him, a thing where
black and white lines come toward you fast, also the fire - blizzard - and lightning
spells don't work on him, also he moves fast and seems to make copies which makes
attacking him hard I hope you didn't use your items because you will no use your cure
spell use the limit attack to get his health down then after it's over attack normally
after a while he will take sora and slowly drain his energy and creates a copy of him you
will control riku the clone will put up force fields like you can to slow you down all you
have to do is send your black lasers at the clone  he will fall over run a few steps then
use the laser thing to stop the clone do this until you get to where sora is and press the
triangle (note:the clone has unlimited life so don't try and kill it also this happens
only once)you save sora and you are controlling no one just watch riku do damage to the
boss you will no when it is over because you will control sora again now the bosses
attacks are different he will be flying around the room (the best way to deal damage him
is to use the limit attack) his attack will be either to send lasers at you or send a
whole ring of lasers around when he sends the ring they will be still until you hear him
say fire then either jump or use the reflect spell when he is even lower on health the
room will turn black and he will send a million lasers at you all you do his keep hitting
the x and triangle button to reflect the lasers so sora and riku don't get hurt keep doing
this until you can't control sora again then watch sora attack the boss it actually does
damage when this is done the boss will be staying still in midair at real low health just
attack him a few times and he dies and if this worked Congrads you beat kingdom hearts 2
