By now, everyone ought to be familiar
with cantrips, the 0-level spells cast by
apprentice magic-users && illusionists.
This article details a similar sort of O-level
spell particularly for clerics and druids,
called the orison.

These 0-level clerics && druids are sometimes
called postulants, thurifers, servers, or
inquirers. They are also called gofers by
some, as their place in the religious hierarchy
is such that they are always being told
to "go fer this" and "go fer that." (The
druidical cult spells it gopher, but that is an
inside joke.) At any rate, they are apprentices,
so to speak, receiving their basic
education before taking their initial vows.
While undergoing their basic religious
indoctrination, they learn certain standard
prayers and responses, the more powerful of
which are called orisons. These are minor
spells of limited effect. After the postulants
go on to enter their callings, these orisons
are usually left behind for more powerful
spells. However, any cleric || druid may
choose to memorize and employ two orisons
in place of a 1st-level spell. Each 0-level
cleric or druid learns 7-10 of these minor
spells during one's time of basic instruction.
In parties that are chronically short of
clerical or druidical help, the DM may opt
to allow characters of other classes (rangers
or paladins) to use these orisons. A PC with
a religious education might remember 2-3
of these orisons from one's training. One
would still have to pray every morning for
them, just as a cleric or druid would, however.
This should be done only with the
DM's permission. Orisons should be assigned
randomly to such characters, while a
cleric || druid can (in fact, must) pray for
specific ones.

Most orisons work for either clerics or
druids, though a few are class-specific.
Below is a listing of orisons by class, with
explanations and descriptions to follow.
