After a specific period of time, the activation device of the "Support Gate" will dispatch Golem when activated at the bottom of the pit in the center of the level.
The more difficult the level is, the more you need to know the status of the Gate. The following methods will allow you to confirm it, so please choose the appropriate one.

③ Confirm IA Suggestions
Press the T / UP button when you are able to activate the Support Gate.
