This listing has been provided by quick reference when specific information about a cleric's religion is needed.
Deities are arranged alphabetically within their pantheon, except that the most important deity is listed first.
The information presented here is to be used as guidelines only -- all clerics of one deity will not necessarily dress identically, for example.
Rank within the temple is often differentiated by variations in color, lining or stripes, etc.
Special sacrifices and holy days may be ordained at any time, or the pleasure of the temple (or its deity).

SPHERE OF CONTROL: This refers to the item, condition, or element over which the deity exerts some measure of control (e.g. Air, Rain, The Hunt, Affairs of the Heart, etc.).

ANIMAL: The animal or animals listed here are the ones most commonly associated with or sacred to that deity.
Clerics of this deity will often protect this type of animal.
Some deities are not associated with an animal, however.

CLERICS: This describes whether the clerics of this deity can be male (M), female (F), or non-human (N-H).
 

Q: Can a character worship a deity
from the pantheon of another race?
Why or why not?
A: Yes, he can, but he might find himself
outcast, accepted neither by his own race
nor the race associated with the deity. This
depends on how appropriate the deity is
for the character. The Greek deity
Hephaestus, for example, is very appropriate
for dwarves or gnomes. Likewise,
deities who are associated with a particular
class are generally appropriate for any
character of that class regardless of race.
A dwarven worshiper of a giants? deity,
however, is likely to be unwelcome wherever
he goes. Clerics are a different matter;
refer to the individual descriptions of
each deity to determine which races the
deity will accept as clerics.

PLACE OF WORSHIP:

This gives the most common locale or construction,
whether natural or man-made,
in which clerics of the deity gather (with or without a congregation) to worship that deity.
 

"Fifth, sixth, and seventh level spells can be given to the cleric ONLY by the cleric's deity directly, not through some intermediary source.
Note that the cleric might well be judged by his or her deity at such time,
as the cleric must supplicate the deity for the granting of these spells.
While the deity may grant such spells full willingly, a deed, or sacrifice, atonement or abasement may be required." - PLAYER'S HANDBOOK, CHARACTER SPELLS.

<as a rule of thumb, if you miss a sacrifice, then you lose one level of spellcasting ability>
<e.g. if you miss the monthly sacrifice during the full moon, and you are a 5th level cleric able to cast 3rd level spells, then you can only cast 2nd level spells until the situation is rectified>

<as a rule of thumb, if you are not wearing your head & body raiment, then a further -1 on your maximum spell level>
<e.g. the cleric in the above example would not be able to cast any spells (unless 0-level spells are used in the campaign)>

<another way to rule the above is with the PR -- Performance Rating -- that gets used in the figuring of Training Cost>

<sacred animals & deities were added throughout the books>

Kevin Hendryx: A lot of contributions were made at each stage and there was not always a clear division of labor. The amount of work required might vary depending on the nature of the project, the completeness (or lack thereof) of the original design, and format requirements or other marketing aspects. Development also helped to proofread bluelines when Production was swamped; and Design or Production would help Development playtest when required. Everybody pitched in with less formal playtest sessions in the off-hours. Sometimes Development would have to create extra material to flesh out an incomplete design; I remember Evan Robinson and I compiling the clerical reference charts at the back of Deities & Demigods one Saturday afternoon. I designed the town sections of AD&D module A3 for commercial release and Paul Reiche largely rewrote the Gamma World: Legion of Gold module from a Gygax early draft, including designing from scratch all the three mini-adventures; I then extensively edited the whole from the separate raw drafts. (My original edited ms. was sold to a collector on the West Coast in 1998.)
