Oriental Adventures campaigns set in Rokugan usually forbid creatures from taking levels in the cleric class, and the cleric class is "usually not available [in Oriental Adventures campaigns set elsewhere like Mahasarpa], but check with your Dungeon Master." Instead, "[s]hamans are the Oriental Adventures version of clerics" (Oriental Adventures 32).
The shaman (Oriental Adventures 22-24) picks two domains at level 1 and a third domain at level 11. The class's Spirits, Domains, and Domain Spells class feature calls these domains only domains, but, later, several unique domains—like Ancestor, Fury, Hero, and Meditation (OA 86, 87, and 87, and the Oriental Adventures Web enhancement "The Mahasarpa Campaign" 8, respectively)—are listed under the heading Shaman Domains.
Are these shaman domains just like cleric domains but under the heading Shaman Domains because there are typically no clerics in an Oriental Adventures campaign, or are the shaman domains an exhaustive, all-inclusive list of the domains available to a shaman, completely different from domains under the heading Cleric Domains (like those on Player's Handbook 185-9)? That is, specifically,…
- Can a shaman pick domains from the list of cleric domains instead of picking from among just the domains listed under Shaman Domains?
- As per the Player's Handbook, can a cleric that's "not devoted to a particular deity… select… domains [that] represent his spiritual inclinations and abilities" (32) from among domains listed under the heading Shaman Domains?
Answers relying on experience and careful reading are fine, but I'd like answers to make a good faith attempt at determining the rules-as-written before delving into speculation or explaining house rules.
Note: The domains Hero and Meditation, for example, include interesting spells that are otherwise unavailable to the typical cleric, like, respectively, giant size and that art thou. The article "Oriental Adventures: Eastern Flavor" (the ersatz 3.5 revision for Oriental Adventures from Dragon #310 32-48) updates only the shaman's unarmed strike damage so that it improves as the shaman advances in levels (yay?) and the shaman's list of martial arts feats; with that in mind, I don't think this question needs the dnd-3e tag despite Oriental Adventures having been published during that era.
