How to get a gold laurel wreath at Arlon's Lunar Sanctum?

I have played this level multiple times, and I cannot seem to find everything in that level. Could someone point out where all of the treasure boxes and intensity gates(If there is any for this level) are?

• In the first mirrored room, the false wall on the left has a chest behind it. (May require 5.0+ - sometimes I've had it only spit out hearts.)
• Rather than go in the door after the bridge where Palutena sneezes, go around behind it to find a chest.
• There's a chest on a platform only reachable by an Exo Tank jump, in the outside area. You do not need to boost to make the jump.
• You need to take out the enemies on the spinning platform near the end of the level to make another chest appear.
• Right before the boss, turn left to find a level 7 intensity gate.
