Got the travel items finished. These will need to be in a player's inventory in order for them to access certain areas on the map.
In order:
Flight potion for Sky Isles
Machete for swamp and jungle
Magma ruby for Ash Isles
Compass to access any part of the wilderness
Snow Boots to access Fraust Tundra
Moon clock to access Crescent Island
Golden Ticket to access Myth Islands. Donator only item
These will be found in shops but if I can implement quests some of them will be obtainable through completing quests.
