Little stuck and more trapped areas

[Hguols]

...Whenever you use the Staff of Invoke Winds on the Insignia of Winds, you have to hold your examine button while you move to get the benefits of the spell.

You can "run" like the winds.

Once you find the switch that raises the gate, you'll be able to run/dash (not walk) under the gate... into the room to apply the Trismegistus's.

...and then to the last area of the game! The Grimoire Grand Hall!
