Aetheryte Crystal teleport NPCs
Anyone who plays this game on a daily basis know Anima does not regenerate at a rate that allows for easy or even PAINLESS travel.
Place NPCs at Aetheryte crystals in the cities and at the camps that will for a gil fee teleport the player to any other Aetheryte crystal.
This provides a gil sink. It will also spare players the wasted time of running from anywhere else to Gridania when they are out of anima.
IT won't break the game, Aetheryte camps to Aetheryte camps or to the cities only. There will still be plenty of time wasted as players still have to run to their final destinations.
