The Clue Revealer was a very late addition to the quest.
It was made so that people would be able to do the sidequests easier.
There are also 4 spots where you can get further assistance,
These are as follows:
- Labrynna Post Office north of the Black Tower.
- In hidden room in Farore's House.
- Behind a bookcase in the Korok's house in Forbidden Forest.
- Crystalline Flame in the clue house east of Veran's Castle.
The trading sequence switches worlds after every trade.
Your next one will be as Din.
I wanted Error to have dialogue but couldn't quite figure out how.
Also, I don't know why that clue glitch happens.
The code is really convoluted and prone to issues.
There is a specific level of progression to the optional bosses, with increasing difficulty at each one.
No, I haven't seen that glitch before.
Nor do I know what might have caused it.
By the way, that cave where you swim is not the end game.
It's the path to something else, which is required for the post-game.
