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.
