Hubs and waypoints

Each act has a hub: a Tibia city (the tutorial's hub is Gullrest Camp, The Wrackline and Gullrest Camp) where you shop, rest and talk to the people who send you onward.

Act	Hub
Tutorial	Gullrest Camp
I	Thais
II	Carlin, then Ab'Dendriel
III	Venore, then Kazordoon
IV	Port Hope (Liberty Bay as a second hub)
V	Ankrahmun, then Darashia
VI	Svargrond
VII	Edron, then Yalahar
VIII	Rathleton
IX	Farmine

What a hub gives you

Full heal and flask refill. Walking into a hub temple area restores life and mana, and your flasks are refilled for free (The flask belt). Nothing refills inside a map.
Shops that sell bases up to the act's tier, flasks, Scrolls of Wisdom and Portal Scrolls (Vendors).
Quest givers for the main story and sub-quests (Sub-quests).
A map device, a globe beside the temple, once you have maps (The map device).
Respec is done in a hub (Passive points and respec). The spells window, by contrast, works anywhere (Learning spells).

Waypoint stones. A waypoint stone stands beside each hub temple and at the key zone of an act. Touch it once to unlock it. Travel between unlocked waypoints is gated by your campaign progress: a boat or carpet to Svargrond or Rathleton refuses you until the story reaches that act. Monsters scale with the area, so a zone far above your level is dangerous (The campaign: acts and hubs).

Hub rules. Trading happens in hubs (Trading), as does changing your ascendancy and respeccing the tree. Some of these actions are blocked inside maps.
