List of all Final Key locations?

[fefnir3284]

I cant find a guide for all Final Key Locations.

All I know is the First Castle jail, the 2nd Castle's basement, the yellow orb night time jail fight, and the southern isle shrine (that allows only one person in).

What other locations are there?

I haven't been through this version so some names will be off but..
Aliahan Castle prison,
Shrine of the Plains (by Reeve, there's a prison door there, unsure if there is anything in there),
Romaria Castle basement in the SW corner, and in the NW corner,
Romaria Outpost,
Teleport Shrine,
Wayfarer's Shrine,
a house in Muor (called something slightly different in this),
Theddon,
Lancel (the thing you call the southern isle shrine),
Pirate's Hideout

Those all have an item or a monster to find, then the game assumes you have the key by that point.

There might be some new little secret spots possibly, I just got the Magic Key in my single player playthrough.

Unfortunately the ultimate key locations after Romaria (so excluding Aliahan, Plains Shrine) are mostly locked off with story line events. A cat sleeps outside the door of the Wayfarer Shrine, guards stay at the doors of the Romaria Outpost, etc.

Meaning even if you get (or borrow a character with) click you are still locked out of most things until you get the ship. At that point the cat / guards go away, because you have the ultimate key available to you in theory.
