help with Golden Sun:The Lost Age

[Wild Eagle]

I just got tremor but I don't understand how to use it. There is a door I need to get by but when I use tremor the two sides just shake and don't fall. How do I use tremor to make the door fall?

[Jigglyangel]

Can you specify what door you are at? There is probably a different way to get through it.

[Azure Pathos-Sketchit]

You are in the Madra Catacombs, right? That sounds like the door to the summon tablet of Moloch. When you press A at it, does it bring up the menu? Well, then, you need to find the Ruin Key to open it, but it is only reachable when Piers is in your party. You need Frost to get to it.

[Musourenka]

Tremor is used for two things: Making items fall off of objects by shaking it, and luring out Djinn that hide behind statues.

I can't think of anything else you use it for.
