Infinite Shelters:
------------------ 
Go to Guardia Forest in 600 AD. Once inside, take the first right, and go to the 
upper path. While in the small clearing, look for a bush in the upper left. Move 
next to the bush, and it will begin to shake. Press A, and a monster will pop 
out, leaving a Shelter as it runs away. Get the Shelter, then leave the forest, 
and reenter. Repeat this as many times as desired.


Infinite Strength Capsules:
--------------------------- 
When on the Black Omen, you will encounter a Blubber Hulk (which at first looks 
like a tornado on the ground). Approach it, and have Ayla use Charm to get a 
Strength Capsule. Then, run away, and go back through the door you came through 
(with the two Nus), and repeat as many times as desired.
