Expansions
Do I have to buy the expansions?
No, all of the expansions function independently with the exception of certain quests (particularly class epic quests) that require you to visit lands (zones) included only in an expansion. Most of the expansions add a continent or set of zones to the game world and you can only travel there if you have that expansion. Tradable items are unaffected.
How does it work with races introduced in expansions?
You can see and interact with them but you can't choose to play as one unless you have the appropriate expansion. For example, without the Ruins of Kunark you can't select an Iksar at character creation. The following races were added with an expansion (alphabetical order): Drakkin (The Serpent's Spine), Froglok (Legacy of Ykesha), Iksar (Ruins of Kunark) and Vah Shir (Shadows of Luclin).
