Coliseum Overview
First things first, check under the statues on your left and right to find Blue Trinity you can use to reach some items - the one on the left nets you a Mythril Shard, and the one on the right will net you Dalmatians 22 - 24. There's a chest behind the pillars to the left of the door - it contains a Mega-Potion. When you enter the double doors, talk to Phil, who asks you to move the stone slab on the wall - try to push it until Sora says it's too heavy. Talk to Phil again, and you'll be allowed into the trials. Unequip Vortex if you have it equipped - it's more trouble than it's worth during the trials. You need to break 20 barrels in 30 seconds - first, hit the middle three barrels until you finish up the combo, and keep moving in a straight line to destroy the barrels. Next, you'll need to break 25 barrels in 60 seconds - the barrels are spread out and on different platforms. Break the barrels around the edge, then jump onto the lowest platform and work your way up, breaking barrels as you go. At the top, hit the barrel into the one on the floating platform - you can also use Fire spells to break it. Now, you can re-equip Vortex - talk to Phil, and he'll give you the Thunder spell. Go outside and talk to Hades, who gives you an Entry Pass - head back into the lobby and show it to Phil to get into the preliminaries. The preliminaries are tough if you haven't been grinding for levels - you'll fight through seven battles without a chance to restock your inventory. You'll fight six battles against Heartless enemies, and the last one against Cloud - you don't have to win against Cloud, but you do have to win the first six to get to him.

Preliminaries
You'll fight against a new enemy type, the Blue Rhapsody - 24 HP, 11 ATK, 10 DEF, and 1 EXP. To defeat them, target them with Fire, and watch for their drops of HP and MP balls. Below are the six rounds and what enemies you'll face.


 * Shadow Scout: Soldier x4, Blue Rhapsody x3
 * Sinisters: Shadow x10, Blue Rhapsody x3
 * Heat & Freeze: Red Nocturne x5, Blue Rhapsody x5
 * Shadow Platoon: Shadow x2, Soldier x2, Red Nocturne x3, Blue Rhapsody x3
 * Blue Revenge: Blue Rhapsody x9
 * Big One: Large Body x1, Red Nocturne x4, Blue Rhapsody x4

BOSS FIGHT: Cloud

 * Stats:300 HP, 11 ATK, 10 DEF, 80 EXP

You don't have to win this fight - if you do want to win, though, you should be at least level 15 to make it easier. You'll also want to have lots of Potions and the Dodge Roll equipped. Lock-on to Cloud and keep it locked - when he begins his lunging combo, hold one direction and continue performing Dodge Rolls to avoid the attack until he's finished. When Cloud leaps into the air, wait for him to hit the ground, then Dodge Roll away so you don't get hit - then lay into him with some combos. When he starts lunging, perform Dodge Rolls as explained above, and wait until he jumps again. This is the easiest method of defeating him - just be ready to heal if necessary.

Coliseum Overview II
When you're through fighting, you'll be back in the lobby - if you won the fight against Cloud, go ahead and save your game, then head back in to fight Cerberus after restocking your inventory with some Potions. If you didn't win the fight against Cloud, head back to an earlier part of the game and grind for some levels until you're three levels or more higher than what you are currently. Then, return and fight Cerberus - be sure to save your game first, either way.

BOSS FIGHT: Cerberus

 * Stats:600 HP, 11 ATK, 10 DEF, 200 EXP
 * Drops Inferno Band when defeated

You'll need to jump to hit any of Cerberus' heads - any of the heads can be hit to bring down his HP. He has four attacks he'll use, and all of them are easy enough to avoid. His first attack is to shoot fireballs, target them and use Dodge Roll to avoid at the last moment. Cerberus' second attack starts with a roar, then he begins to gnash his teeth at your party members - wait off to the side while Donald and Goofy get attacked, and wait for the head closest to you to bite down. When it does, jump in the air and hit it a few times, then wait for the next time it bites down. The third attack starts with Cerberus rearing up and slamming into the ground, which creates a shockwave that shoots out from it - jump to avoid it easily. The last attack Cerberus uses is a black fog that comes from his mouths, and will rise from underneath you to cause damage if you stand still. Use Dodge Roll to roll around the area while targeting Cerberus to avoid taking any damage. So long as you use Dodge Roll with some amount of skill, you should be able to get out of this battle without being hit. Alternatively, you could just jump on hs back util he starts biting, then go in for the kill. When you defeat Cerberus, he'll drop the Inferno Band.

Coliseum Overview III
Talk to Phil to receive the Hero License, and Cloud will show up to bestow the Sonic Blade ability to you. Equip it - it's very useful. Time to head back to Traverse Town - use the double doors to leave.

Return to Traverse Town II

 * Items Obtainable: Megalixir, Orichalcum, Curaga-G, Postcard x2

Now that your back in Traverse Town, head to the 3rd District and look in the corner to find a pipe with a broken wire sticking out - hit it with Thunder to hear a chime. Now go to the 2nd District and enter the Gizmo Shop - clear out the enemies and take a look at the newly-raised platforms. Use the platforms to reach the upper level of the shop, and step on the three switches to hear another chime. Drop down to the lower level and wait for the clock to stop - examine it for two Postcards. Mail them in the 1st District to get a Megalixir and an Orichalcum. Drop off the Dalmatians you've saved thus far at the Dalmatian House to receive Curaga-G, upgrade your equipment, and head back to Wonderland.

Return to Wonderland

 * Items Obtainable: Shell-G, Thundara-G

Stop off at the Queen's Castle and enter the Lotus Forest - jump up the two mushrooms in the faux lake on your left and drop into the clearing. Use Thunder on the nearby Bellflowers to get Shell-G. Jump back out of the clearing and head to the back of the forest where the three mushrooms are - jump onto the smallest, then jump to the left so that you land on the branch with the acorn. Jump again to the door to enter the Bizarre Room, and head through the painting to enter the Secret Place. Shock the flowers to get a Thundara-G. Leave the Lotus Forest, and get back to the Gummi Ship - try your hand at ship building if you like, then travel to the last mystery world on the world map - Deep Jungle.
