The doorway in “Chamber 2″ has brought you to the mid-level of “Chamber 3″. While fighting and traversing in this area, it is important not to fall off, as this will force you to return to “Chamber 1″ and start all over. Use the barrels nearby to reach some of the higher platforms, like the one with a Treasure Chest containing Dalmatians 76, 77, & 78. Hop back down to the mid-level platform and proceed through to “Chamber 2″ (this is not the same door you used to enter “Chamber 3″ though. There is another door that also leads to “Chamber 2″ directly across from the door you used to enter “Chamber 3″)
Back in “Chamber 2″, it is important not to fall off this higher level. Knock out all of the Heartless that appear and then jump from atop one of the barrels to reach the platform across the gap with a Treasure Chest containing a Megalixir. Jump on top of one of the barrels on this platform to jump back across the gap and use the nearby doorway to enter “Chamber 5″
Clear out all of the Heartless in the room and head straight through to “Chamber 6″
Entering “Chamber 6″ will drop you right in a battle with some Barrel Spiders. Take them out, but be sure not to fall off the top step in this area and fall to the lower level. You will not be able to get back up and you’ll have to pretty much start all over. Once you’ve made your way down the steps, taking out all of the Heartless that show up, collect the Dispel-G from the Treasure Chest nearby. Head back up the steps and climb up on one of the remaining barrels to access a platform above with a Treasure Chest containing another set of Torn Pages (which you’ll need to complete 100 Acre Wood). Drop back down and head through the doorway at the bottom of the steps to access “Chamber 5″
This lower area of “Chamber 5″ is filled with Heartless, so clear them out when you first enter. Use the Blue Trinity Mark to obtain a ton of Munny and a Cottage. The nearby Treasure Chests contain a Dispel-G and a Mega-Ether. Use the nearby barrel to jump up to the higher ledge and take out all of the Heartless up here without falling off the edge. Use the barrel near the doorway to reach the higher platforms on the walls. The Treasure Chests up here contain a Mythril and Dalmatians 79, 80, & 81. Hop back down and go through the doorway you passed earlier to access “Chamber 4″
