quote gui_dez_wizard14

Here is how to get the 4 bottles where you can stock potions, faeries and other things.

1: One man in Kakariko Village sells one for 100 rupees. He can be found easily since there's a lot of bottle around him.

2: Still in Kakariko Village, search for a hidden entrance behind a big house. Inside, there's a chest, which contains the second bottle.

3: Go in the river in north-east Hyrule. Swim under the bridge to find a strange camper. Talk to him and he will give you the third bottle.

4: After completing the fourth Temple in the Dark world, go to the place where there is the Blacksmith's House in the light world. There will be a locked chest in the broken house. Take the chest to the man at the entrance of the desert, without running. The man will open the chest for you, revealing the fourth and final bottle.
